Error when saving All Style Options

[Frank Woolf]

I have a child style of Legacy (called BlueCream). This child style has two child styles which work fine.

I recently upgraded to vBulletin 3.6.4

I can create another child style of Blue Cream but when I try to save the "Main CSS" or "All Style Options" of the new style I get the following error even if I made no changes.

Warning: implode() [function.implode]: Bad arguments. in /admincp/css.php on line 103

 

    Rebuild Style Information

        Updating Style Information for '' and child styles...

            * ...
              Fatal error: Invalid styleid specified in /includes/adminfunctions_template.php on line 327

I asked for help on the vBulletin site and they suggested I remove all the customization work I have done. It was working fine with the customization before the upgrade and I have done months of work doing the customization so it will be a huge job to undo it all.

Can anyone suggest a way to fix this without undoing all the customization?

Thanks
