I don't know that it's a "problem" as such - just a size limitation.

The new server does have more drive space than before IIRC, but it's not cloudy infinite.
So I don't expect we could raise the limits much.

Just testing that MathJax is still available:

$$ ax^2+bx+c=0 $$

Yes, cool  :)

Are the PDF attachements also fixed?
First I have heard of it... whats the problem?
PDF attachements never open in Acrobat. Every other website works but not EEVblog. AFAIK this is a well known problem for EEVblog users so most refrain from attaching PDFs.

For example the PDFs attached to this message:
https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/msg1371771/#msg1371771
Firefox (the latest version) says the file type is unkown and wants to open it with a text editor.

OK just checked on this thread ^.
File downloads fine and it opens in a tab in your browser fine too. In Chrome with a right click on the downloaded pdf you can set "Always open in Acrobat" and when set it does just that.

I guess Chrome is doing something non-standard then and tries to guess based on the extension. According to the specs the webserver is supposed to let the browser know what kind of file (mime-type in the HTTP header) it is receiving regardless of the extension. If that is broken a browser gets a binary blob with unknown content. BTW the same goes wrong when people attach pictures. Firefox can't deal with those either probably due to the missing mime-type. As I wrote before: EEVblog is the only website I visit where this doesn't work properly.

Content-type is not a required header according to the specs, if your browser is misbehaving either it's a bug or you have a plugin installed that is messing things up:

https://tools.ietf.org/html/rfc7231#section-3.1.1.5
Quote
   A sender that generates a message containing a payload body SHOULD
   generate a Content-Type header field in that message unless the
   intended media type of the enclosed representation is unknown to the
   sender.  If a Content-Type header field is not present, the recipient
   MAY either assume a media type of "application/octet-stream"
   ([RFC2046], Section 4.5.1) or examine the data to determine its type.

I have plain & simple Firefox (the most recent version but previous versions had the same problem) with ABP as the only extension and no tweaking of anything. Firefox says it can't determine the type of the file. And I think you are mis-interpreting the specs. It says the sender (server) should indicate the content type unless it really really really can't do it. It also says that the recipient (browser) may choose what to do when the content type is unknown: treat it as a blob or try to guess. So if you want the transfer of files to always work over HTTP then there is no other option than having the webserver supply the correct content type.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

Quote
3. SHOULD   This word, or the adjective "RECOMMENDED", mean that there
   may exist valid reasons in particular circumstances to ignore a
   particular item, but the full implications must be understood and
   carefully weighed before choosing a different course.

I am not saying that this should not be fixed, I am however saying that it is not a critical problem nor high priority.

File type is not detected using the extension under Linux, it is a bad practice to do so on any operating system. The mime type is detected by scanning the file headers for known signatures, this imposes additional server load. Assuming a file is what it is based on extension is a dangerous practice and can lead to downloading a "PDF" that is really a malicious file, simply because the file extension was trusted.

So if you want the transfer of files to always work over HTTP then there is no other option than having the webserver supply the correct content type.

But the web server doesn't know the correct content type. The file was uploaded by the user as an attachment to a post, and the only information provided by the user was the file name and extension. When you view the post, you get back the information originally provided; no more, no less.

The only way the server could indicate that the attachment is a PDF file is to look inside the file and interpret the contents, or to look at the extension and associate .pdf with a PDF file. Both of which the browser can do just as well.

In this case the server has no business deducing or guessing, it should just hand back the data as it received it with the same file name. So I think the server is behaving as it should.

The makers of Firefox (not exactly a niche browser) seem to have a different opinion so don't shoot the messenger. Life sucks and sometimes you have to fix things which are not really your problem to start with.

I think someone's missed the point. The writers of SMF obviously took the decision that, when an end-user uploads content, they would not make any assumptions about what the MIME type of that content was. To take an uploaded file and assume the MIME type could completely misrepresent the content type. Relying on the fact that someone puts 'pdf' or 'jpg' on the end of a file could allow all sorts of malfeasance - see below (a benign example):

IMHO the application receiving the file should do the check AFTER it has been scanned automatically by the virus scanner. There really isn't any need to be more secure than necessary because that just causes extra nuisance with zero added security.

Unfortunately due to the huge jump software versions this can not be done without causing some downtime.

Likely an overlooked setting to be updated, I will try to reproduce and correct it. Thanks for reporting it.

Edit: I can not reproduce it, it sounds like you have it cached somewhere, perhaps your ISP has cached the error from during the update.

Interesting, mine's unchanged too like Wilfred's.

I retain mine after the upgrade. But I also never got the ability to move topics that was introduced before the move. So my experience may not be the most reliable guide.
There are a couple of ways to have Move Topics visible and everyone has it by default at the bottom left in the first page of a topic they have started. In 'normal' forum view it's just above 'Quick Reply'.

No, it is not a cache issue imho. I have the same behaviour here: Linux/Windows + Firefox works perfectly well but with my iPad 4 and Safari I get this "Database error". It needs reloadings from 1 up to 20 or 30 attempts until I get what I'm looking for. It seems also, that it is some kind of load dependend. I thought first, it could be a cache thing (DNS, browser etc.), therefore I was waiting for the TTL to become obsolete. But it seems, it is still coming up with this database error.

Me too!! Meanwhile it is online possible to login from my S7! IPad, Linux, Win10, different browsers have all passed one after another with this database error!
And I think, this is the last time, i'm able to login now....

Ok, i'm in with my desktop again. But it tooks more than ten attempts in a row.
Maybe a server overload, storage misconfiguration?

Ok, I will have another dig though, it does seem very odd that it intermittent as everything is in sync.

Certainly not overloaded, perhaps there is a plugin still trying to use the old database configuration.

I saw the database error a few times shortly after the server move, but, unlike others, I haven't seen it for a few days,

On the subject of 'ignore topics': I turned it off, and turned it on again in my profile and the option reappeared. So if anybody has the same problem "turn it off and on again".
Anybody got a syringe I can use to squeeze the magic smoke back into this?
