XF 1.5 Server Error Log - Invalid Math expression

[Tyluur]

Today I transferred my forum from a previous domain/database over to my new domain/database/host. The change was successful and I was able to get all threads/topics/usergroups etc synced over. However I ran into this error when I did actions like delete a usergroup or install a new theme. When I installed a new theme, I got a white page instead of the new page when I tried changing over to it.

Error info:

XenForo_Template_Compiler_Exception: message.css - Line 27: Invalid math expression - library/XenForo/Template/Compiler.php:991

What method did you use to transfer the database to the new server? Shell commands are the most reliable method:

Make sure the new server meets XenForo's requirements:

Try reverting the template named in the error:

Admin CP -> Appearance -> Templates -> message.css

You can also try deleting the deferred tasks:

Hey thanks for the reply,

To transfer to the new server I simply exported the sql database and imported it over on my new server using phpmyadmin. Then I changed the info in config.php.

These requirementes are met.

I've just ran the query to empty the deferred queue, and then I tried to import the new style and got the same error.

I'll now upgrade to the newest xenforo and see if it'll make a change. I'm on 1.5.1. right now.

You've most likely upgrading to a style designed for a more recent version; there's something supported in 1.5.9 that isn't supported in 1.5.1 that can trigger an error like that. So upgrading would be the way to resolve it.

 

[Tyluur]

Upgraded and solved.


Req. Close

 

[Degrinch]

If upgrading is not an available option at the time?

 

[Mike]

You'd need to use a style that's designed for your specific XF version (or at least a version prior to one that uses the new option).
