I have been driving myself nuts. My database will not sync. I have 2 others that sync just fine. I have enough memory. I have tried different browsers. I have deleted database and restored. In a pro-gallery, in the editor preview, links work, live site they do not.
Starting over is going to set me back weeks. I have restored different versions as well but of course, lose all my work if I go back to the last time the database synced which was more than a couple of weeks ago.
If you created any data hooks, I’ll suggest to rem remove them and see if it helped (maybe you had an error in your back-end code). If you don’t have data-hooks or if it didn’t help, you should contact Wix support.
