We recently updated our moodle from 3.4 to the latest stable version 3.5.2+. In our moodle 3.4 we had certain indispensable plugins that worked correctly. These plugins, according to moodle.org are compatible with Moodle 3.5 so, theoretically shouldn't be a problem, right?
When updating to 3.5.2+ these plugins automatically stopped working (I attach a screenshot of how they appear in the plugins overview section).
I thought I'd uninstall them and install the latest version that appears on moodle.org. However, when I want to install the plugin I get a validation error.
Install plugin from ZIP file
Validating block_dedication ... Error [Error] Write access check [/var/www/html/moodle16/blocks] Installation aborted due to validation failure
How should I proceed? Could the problem be that I'm using 3.5.2+ and not just 3.5?
Thank you in advance!
