Attaching large images gives blank page

[Rickard]

I am having problem with attaching large images to posts in my forums after mowe to cloud based server.
The server people have lifted the attachment limit to 50 Mb, this should not be the problem.
I have (a quite old) module, Resize Attached Images, is this perhaps the problem?
I have no limits on images size in the settings.
The page that opens has got URL https://www.poolforum.se/forum/index.php?action=post2;start=0;board=27

I white blank page.

Take a look at your servers error log, is there anything there?

... just to confirm, does the host's php.ini have the following setting ?: upload_max_filesize = 50M

Aleksi is likely to be referring to where the PHP errors are logged.

Working from home today, and have lost my password for cpanel, can not check error log, but have asked the server support to do so.

Since i wrote this i have tried to uninstall and reinstall resize attached iamges i www.atvforum.se and then tried to attach a large image and it worked!
Then i notice that the forum does not work on some pages, for example https://www.atvforum.se/Forum/index.php?action=forum
But if i go to onother page, for example: https://www.atvforum.se/Forum/index.php?topic=57937.msg587560#msg587560
It works.
If i try to add the same large picture, and now it does not work.
Strange, but not unexpected due to a lot of small problems like this after the server change.

What is this about.
Since i can not log in to cpanel, i did no backup, anyone have any idea what happend?

Another issue i have after the mowe to new server with Cpanel is that changing theme throuht admin panel somtimes mean that the server takes away code, and also adds code never earlier been present!
Most obvius this is when adding code with åäö (swedish) then it get all corrupt, and the server deletes a lot of code (not just the rowes with åäö) and adds new code making the forum crash.
Is this a cpanel problem, language problem, or settings problem in PHP or something else?

what are your Admin > Forum > Attachments and Avatars > Attachment Settings ?

screenshot would be the easiest
