Hello,
I apologize for the delay. I was on paternity leave, which is why I couldn’t respond to your message earlier.
Please check your mobile menu overlap issues and the homepage button issues.
The button issues are caused by an override addon. I have added a button addon and linked it to your News and Events page from home page.
Regarding the article you mentioned for editing with SP Page Builder: this article was created using the Joomla editor. That’s why you cannot edit it with our page builder. To edit with SP Page Builder, you will need to create the article using the page builder first — then the SP Page Builder editor will be available.
Best regards,
