Hello there

I'm using mybb 1.8.5 on a dedicated server. For the last 2 weeks I'm getting "Internal Server Error" when trying to upload pdf files larger than 6 MB

checked php.ini for changes... but it is  good

post_max_size = 50M
upload_max_filesize = 20M
memory_limit = 128M

Settings>> Attachments in Mybb Admin Panel shows maximum size for .pdf is 12 MB.

Please tell me where to look for the cause of the error..

Thanks in advance

First priority after this should be to upgrade to 1.8.10, 1.8.5 is over a year and a half old.

The best place to look would be the Apache error logs on your server.
