#1569 – White screen editing joomla article

Hi

This would indicate either some error during installation (some parts of sh404SEF are missing) or some mismatch in versions.

What are
- sh404SEF exact and full version?
- shLib system plugin full version?
- do you also have Josetta installed?

Hi

hmmm that sounds pretty weird.
What Joomla version is this? and what editor are you using? does it happen as well with other editors.

Also, you said "when the problem started". When did this started exactly?

Hi

ok, so it sounds more like a server setup issue (assuming the live and local copies are identical in terms of plugins - system plugins specifically).

What are the local/love PHP version? if you use opcache on the live server, can you empty the opcache cache? (normally when sh404SEF is installed, it clears it, but maybe that failed somehow).

Another thing to look at may be the system plugins ordering. Are the same locally and live? the plugins involved are sh404SEF, shLIb and the system plugin for JCE or Rokpad.

Hi

No, there's nothing that gives any clue on why this is happening on your server.

Is your local site on windows? this could hint at a capitalization issue (some folder names not having the correct case?) but that would not be consistent with the problem only appearing when editing articles.

Maybe we can get a bit more info like this:
Can you replace this line:

$link .= '<link rel="stylesheet" href="' . ShlHtml_Manager::getInstance()->getMediaLink('bs', 'css') . '" type="text/css" />';

with

$manager = ShlHtml_Manager::getInstance();
echo '<br />Manager = ' . print_r($manager, true) . '<br />;
$link .= '<link rel="stylesheet" href="' . ShlHtml_Manager::getInstance()->getMediaLink('bs', 'css') . '" type="text/css" />';

When run, and trying to edit an article, this should either dump a lot of code onto the screen or instead say something similar to "Manager = null".

Another track that can be followed is to disable one by one other system or content plugins. This might be an interference with another plugin loaded on the edit article page.

Hi

Sorry, it seems your last 2 replies (by email) have not been added to the ticket by the cron job of our Akeeba ticket system. I just found them when checking directly our ticket reply email address in GMail.

You said:

Hi,



I am running my localsite on a 100% ubuntu machine.



When I replace the code it creates a white page for my livesite in the frontend, which I cannot allow with Christmas around the corner.



I will start this afternoon to disable the plugins one by one to see if I get a result.



Regards,



François

A white page means a PHP fatal error. Most likely there's a typo in the code. If you temporarily set Joomla "Error reporting" setting to "Maximum", you should be able to see the exact error message.

with Christmas around the corner.

I am confused: are you running this as a "localsite on a 100% ubuntu machine" or is this a livesite?

Hi

OK, glad to hear that. Not sure what solved the problem though, as this was mostly a maintenance release to have separate Joomla 2 and Joomla 3 branches, but it may have to be more with a partial/failed install maybe.
