Weird, the settings should look like this (see image below).
You can try with the tables, but I can’t promise it’ll work. Back up everything first! Just install a new WordPress site, move the tables over, and test.
Note: This issue was caused by some server or software setting that blocks all ajax packages larger than 10 MB. Since the virtual tour config contained a large number of scenes (over 200), the result was the inability not only to preview but also to save such a virtual tour.
Unfortunately, we were unable to precisely identify what is causing the filtering.
