XF 1.3 Upgrade error


Active member
Just uploaded all the files and begin the update, when I got this error message. Any help would be great.

Fatal error: Class 'XenForo_Template_Compiler_Function_CheckedSelected' not found in /home/xxxxx/public_html/library/XenForo/Template/Compiler.php on line 149

I reuploaded the whole compiler and it worked, went to log into the admin panel and got another error so reuploading the controller admin folder.

Funny thing was that not everything uploaded which was why I was getting the errors. I always upload everything in the folder, I guess it was just a hiccup. Thank you both though very much.

Which FTP application do you use?
If you run Windows, I recommend WinSCP.
Never use Filezilla, it is notorious for issues such as this.

There are some errors in there having to do with the add-on Widget Framework. Post in its dedicated support thread for support with it.
