Hello, since today I get the following error messages: Uncaught TypeError: s.tooltip is not a function (line 1) and Uncaught TypeError: Cannot read property ‘hasClass’ of undefined (line 1). Microthemer can not be operated any more. I have already deactivated all plug-ins and uninstalled and reinstalled the Microthemer.
I’m using WordPress version 5.1.1 and Microthemer version This error occurred on my demo page – but I’m afraid that this error could also occur on my live pages. How should I proceed? Could there be a problem with the w3total cache plugin?
Thank you in advance for your help.
Best regards from Austria,
Klaus D.
