Fatal error: Class not found in /concrete/core/libraries/loader.php (since updating to 5.6)
The page where the Date Nave Navigation block is used, I get a total white pagina, with only this error:
Fatal error: Class 'DateNavBlockController' not found in /var/www/domains/parousiawijchen.nl/www/concrete/core/libraries/loader.php on line 402
On other pages, when I try to add a new block, I get the same error.
When I try to edit the addon (I wanted to try to delete it), same error.
I have no idea what to do now? Is the Datenav no longer available in 5.6? How can I either fix or remove it?
If that fails to fix it, have a look to see if you have any 'override' files in [root]/blocks/date_nav. If you do, try temporarily re-naming the [root]/blocks/date_nav folder and see if that clears things up. Overriding in 5.6 is 'stricter' about things and I ran into this problem on a couple of my customizations.
Oh and I think there's an ointment you can buy to treat 'white pagina'.
My problem happened when I tried to run the site on localhost. I can navigate to any page that doesn't contain the problem block, but any page with it gives me the following error:
Fatal error: Class 'TwocolBlockController' not found in C:\xampp\htdocs\mysite\concrete\core\libraries\loader.php on line 420
I installed the site on the actual server in the same manner with the same database and it works just fine. Any help would be much appreciated.
I tired temporarily re-naming the [root]/blocks/twocol directory which contains the particular block that's giving me the trouble.
