Hello all,
After the upgrade moodle 3.4 to 3.7 I got this error on every page:
Fout in de programmeercode gevonden. Dit moet door een programmeur hersteld worden. page layout file [dirroot]/theme/aardvark/layout/ does not contain the main content placeholder, please include "<?php echo $OUTPUT->main_content() ?>" in theme layout file.
I have checked my used theme Aardvark and I thing this is the problem.
How can I switch to a default theme? Can't enter my site so trough PhpMyAdmin?
Please help me out!
Regards
Reinier
