Hello, I have the same error in the forum logs:
"Invalid argument supplied for foreach()" on Sources/Subs.php (Line 3832).
3832: foreach (array_reverse($context['template_layers']) as $layer)
3833: loadSubTemplate($layer . '_below', true);
3834: }
My htaccess file is not empty. It is generated by PrettyUrls mod.
Currently I have 20,000 errors about that line in the logs panel.
How can I fix it?
That means that the foreach was expecting to be given an array to work with but wasn't (probably either an interger or a string was received instead).
Whatever bit of code that is meant to build the $context['template_layers'] array, fails to do so. A quick fix for it would be to locate the code that is supposed to generate the $context['template_layers'] array and have it firstly create the $context['template_layers'] array as an empty array, that way the foreach will always be given an array to work with
Well, $context['template_layers'] in a normal setup is made automatically by SMF... that sounds like a mod is breaking it.
Is it every page or is it specific to certain pages?
Yeah same issue here, it is indeed caused by prettyurls (every page)
