Moodle in English: Error during maintenance: Table 'mdl_block_recent_activity' already exists
Re: Error during maintenance: Table mdl_block_recent_activity already exists Wednesday, 23 June 2021, 7:46 PM Is the upgrade script trying to create a new version of it with my new character set? – No. What this error suggests is 1) the Recent Activity block wasnt installed, 2) somehow its table, mdl_block_recent_activity, was created in the database at some point, and 3) this blocks source code folder is now present triggering the attempted install and failing because of 2). So youre right...
