PHP 4.4 and PHP 5.2.3 under Apache 2.2.4 on ubuntu.

I am running Moodle 1.5.3 and have recently had a problem when updating a course. The $_POST variable is empty but only if a lot of text was entered into the textarea on the form. If only a short text is entered it works fine.

I have increased the post_max_size from 8M to 200M and increased the memory_limit to 256M but this has not helped. I have doubled the LimitRequestFieldSize and LimitRequestLine to 16380 and set LimitRequestBody to 0 with no improvement.

I have googled for an answer but have been unable to find one.

HTTP Headers on firefox shows the content size of 3816 with the correct data, so its just not getting to $_POST.

The system was running fine until a few weeks ago. The only change was to /etc/hosts to correct a HELO issue with the exim4 email server.

I can replicate the issue on a development machine that has exim4 not running so I think it is just coincidence.

Thanks for your assistance.

  1. Could it be not the size related of the post, but how long the line is before a new line. If they use the Moodle WYSIWYG view the html would just get put into one line with no breaks. If you go into html and hit return around every 1000 characters does it work?
