We just inherited a website from another agency that was build with the Page Builder Pro. When saving a page that has an Addon Heading that contains a link that page wil show Error "0 – Object of class stdClass could not be converted to string" on the frontend. The backend editor as well as the frontend editor are working just fine. It’s only the actual page that shows the error.
Pages containing linked Addon Headlines that haven't been saved are not showing any errors.
I tried updating both Joomla 4 as well as the SP Page Builder Pro to the newest version, but the error still shows when saving pages.
