I just got this error after trying to add another theme (stacked)… When I decided I didn’t like it, I removed it from the theme directory and now it won’t select anything and the forum won’t load at all with the following error:
[spGroupView.php] – Template file not found or could not be opened.
The “default” template is the only one that is there in the theme directory so not sure why it’s saying that it can’t be found ?
