Update Toolset Forms and Toolset Module Manager, had this issue with other Toolset Plugins in the last weeks, manual update works, but I need a solution were I can use the wordpress update engine again
Solution:
The solution was to delete the site-key, unregister my site and then register the site with a new key. After that everything worked.
Problem: I am trying to use the thumbnail slider module but the navigation doesn't work as expected and the thumbnail layout is vertical instead of horizontal.
Solution: The thumbnail slider module is heavily reliant on Bootstrap. Unfortunately the Divi theme is incompatible with this library. Use a different slider system that is not reliant on Bootstrap, or prepare to add custom CSS to fix compatibility issues.
