I was able to install Pagebuilder without an issue on a fresh install of Joomla.
I used the same procedure to install in onto one of my production sites and I can not get it to work. I have 6 other sites to do as well and this seems to be a big hassle.
Once installed, when I go to creat a page I end up with a bunch of gibberish and no interface.
I asked for a refund but was told I needed to give this a try first. I am just not excited to deal with this on every site I have.
Thank you in advance for your time helping with this.
