I couldn’t update my site even though my Toolset license was active; it showed the error “Unable to register: Site key not matching.”
Solution:
Unregistered and re-registered Toolset via WordPress Dashboard → Plugins → Add New → Commercial tab → Unregister Toolset → Register Toolset → Get a key for this site → paste the new key and confirm. This resolved the license mismatch error.
Blog preview images appeared stretched on the category archive page, while other images displayed correctly.
Solution:
After investigation, it was confirmed that the affected page was not created with Toolset, since deactivating Toolset Types and Blocks did not affect it and no Toolset archives or templates were assigned. Therefore, the issue was unrelated to Toolset.
I kept seeing a warning that Toolset plugins couldn’t connect to toolset.com due to a site key mismatch, even though the plugins worked fine.
Solution:
Unregistered and re-registered Toolset from WordPress Dashboard → Plugins → Add New → Commercial tab → Unregister Toolset → Register Toolset → Get a key for this site → paste the new key and confirm. The warning message disappeared afterward.
