Hello @freedomdesign,
Thanks for writing in!
Please test for plugin conflict. Upon login I cleared SG Cache and then deactivated all plugin based on the error messages in Chrome Dev tools. Upon deactivating plugins theme options panel is working fine. Please see screenshot link in secure note.
Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Thanks.
