Blank Post When Editing

[invitezone]

Hi all.
I am having a weird issue when I try to edit a post.
The post has text in it but when I go to edit the post the edit box shows blank as if posting a new post.
I have read some stuff on here saying that can be caused by PCRE 8.21, so I have asked my webhost what version I have and this was the reply...

I've checked the issue and as I see you have PCRE 8.31 installed not 8.21, it comes with PHP 5.4 by default, please let us know if you need to downgade any module/programs on your server.

php -i|grep -i PCRE
PCRE (Perl Compatible Regular Expressions) Support => enabled
PCRE Library Version => 8.31 2012-07-06
pcre.backtrack_limit => 1000000 => 1000000
pcre.recursion_limit => 100000 => 100000

I have no idea what to do next.
Can someone please give me some things to check or maybe someone is familiar with this issue.

Thanks for any help anyone can offer.

Did your host just upgrade your server to PHP5.4? If so, tell them to go back to PHP5.3 or tell them to put you on a server running PHP5.3. vB4 is currently not compatible with PHP5.4

You might be able to get around this by going into general settings, and changing the Ajax option to "disable problematic ajax".

We got bumped up to 5.4 for too and it's been a pain, we can't back track, so I've had to live with it. After tweaking the Ajax settings, most of the major issues we were having (editing posts and such) seemed to clear up. Obviously I miss the inline-editing, but it's a small price to pay for now.

ok thanks for the replies.
I can downgrade without too many problems so I think I will just do that.

Thanks all.

I have now downgraded to PHP5.3.3
but now I having some problems that I never had before.
When posting a message I can't paste things in from clipboard.
Also the little picture that you click when you want to add an image no longer works.

Any clues on what I should do?

Thanks all

Create a new style with no parent:

Styles & Templates > Style Manager > Add New Style
Parent Style: No Parent Style
Title: Default vBulletin
Allow User Selection: Yes
Save

Then browse the site using that totally default vbulletin style - do you still have the same problem?

[invitezone]

yep same issue continues on that newly created theme.
this is only since the php downgrade though, very strange.

Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

Also, verify you have all default files in Maintenance > Diagnostics > Suspect File Versions

[invitezone]

done all that and still the same problem.

any further things to try?
Should I consider going back to php5.4 where I only had some mild issues?
