Fatal Error after installing 1.1

[niblem]

Fatal error: Call to undefined function: tp_loadtheme() in /home/globalav/public_html/forum/Sources/Load.php on line 1114

This is the error I receive after I installed SMF 1.1 via webinstall.

I was using 0.9.6 TP

I have read that some servers don't like webinstall, best look/ask over at SMF forums to see if they have a fix

Wrong theme for you setup, Did you use any other theme then DEFAULT SMF Core theme when you installed, you can get this error.
THis have been supported many times before, and i suggest you use the search and read the posts about this issue.

Yes, I use the default theme on my forums prior to install.

Secondly, I did search my exact error, but it came up with no results, sorry.

Do an advanced search or a search from the forum INDEX (forum start page) with this line
*Call to undefined function: tp_loadtheme()*
I got a LOT of hits with how to solve the issue

Did you reinstall TP after upgrading your forum?

Did you reinstall TP after upgrading your forum?

Not yet.  Do you mean just reinstall the latest version?

I'm so very sorry for being alot of trouble, I just get very nervous when it comes to these things because I ALWAYS worry that I'll lose my posts/downloads/gallery pictures, etc when I re-install things.  Low-confidence level
