I have my website 90% built and was adding testimonials to the homepage with the Testimonial Pro addon (already in place with the quickstart install). As soon as I added a photo for the person (correctly sized to 104 x 104) the whole website crashed and showed a "0 Object of class stdClass could not be converted to string" error.
By going into the Pagebuilder Pages section I was able to disable the addon. The front end of the website came back but I was no longer able to edit the homepage using the frontpage editor.
I went back into the Pages section and deleted the addon and now I can edit the homepage using the frontpage editor again. However, every time I go back to the frontpage editor and try to add the Testimonial Pro addon, the site crashes now.
