Blank Page when adding article from front end

I am getting a blank page when adding an article from the front end.

I have tried changing mootools upgrade plugin and turned of SEF. It still doesn't work. I am not sure when it stopped working, but I uploaded 1.5.6 to see if that would fix the problem, but it didn't. I have also used the default template and still nothing.

I don't know what else to try.

Thanks.

did you use flexiaccess ?
did clean you cache and cache expired ?

Maybe it is a system plugin.

Disable/enable SYSTEM plugins one by one and refresh the page, to check if this fixes the problem. In 5 mins you can test all system plugins.

Thanks for you quick replies.
No FlexiAccess
Yes, I cleared Joomla cache, expired cache and browser cache.

I have tested in Firefox and Chrome.

I went through the system plugins one by one, clearing cache in between and other than messing up my site temporarily, it didn't change the issue of the blank screen.

I also re-installed FlexiContent 1.5.6 again.

I added another menu link to "add item" (just in case there was a problem with the original one).

Any other ideas?

I have a very similar set-up on another site and it works fine.

If the error message occurs while printing javascript nothing will be shown.

Try 2 things:

1. Do "view page html source" for the white page, and go at the the end html source and see if there is some error message.

2. Try putting:

error_reporting(E_ALL);

at the start of file
components/com_flexicontent/flexicontent.php

Just after line:
defined( '_JEXEC' ) or die( 'Restricted access' );

Hopefully some error message will be printed.

Regards

I tried viewing source but it was completely blank.

I then added error_reporting(E_ALL); and it threw some errors in one of my modules, but didn't change the blank page. No errors and no content of any sort.

I then investigated the module with the errors and the component which feeds it and disabled those, cleared my cache in both Joomla and my browser. Still blank.

Do you want my login info to take a look?
