I have problem with uploading files via http on sites. Problem is that I can not upload files larger than about 126 KB. Problem is I believe server related because I have few sites on VPS and on all I have same problem.
For example if I try to upload files using widely used PHP contact form, or trough CMS on sites I just get error 500 or 404 page when I try to upload any file larger than about 126-127 KB. If file is smaller, everything is OK.
I uploaded larger files before. I can not tell when this started because I did not tried to upload files for few months. Only I can think off is that it worked before few months before setting PHP with mod_fcgi (maybe this is not relevant at all).
Also there is no any errors, there is no error_log in root of site, or in any other folder.
Is there anything I can check?
