Hi Krileon, thanks for the quick response.
All CB tools were carried out without complaint.
When operating in phpmyadmin there was an error message:
In the table '... acymailing_geolocation' it says
#1071 – Key is too long. The maximum key length is 1000
When I look at the structure of my database, almost all tables have the collation utf8mb4_unicode_ci (even the acymailing_geolocation)
Three tables have the collation 'latin1_german2_ci' These are the tables
comprofiler_plugin_blogs
comprofiler_plugin_messages
comprofiler_plugin_messages_read
a few more tables have 'utf8mb3 general_ci', but no cb-tables
Can I manually change the collation in phpmyadmin?
Thank you.
Jens.
