I recently upgrade from Adaptable 2.2.2 to 3.0.2 (2020073103) on Moodle 3.10 (Build: 20201109) and following this, I can only see a same identical icon in all my block headers - see below.
I removed my customs CSS but that did not fix the problem.
I search the systems settings from anything related to "block header" and "icons" but did not find anything which solve my issue.
Any idea what I am doing wrong?
Thanks in advance and best regards,
