So we had Jupiter theme installed for months. We then updated it to their newest version. The new version requires that you install their bundled Visual Composer plugin, which has been modified in some way from the original.
When we updated theme, the site worked fine. When we installed their version of VC, the websites back end became a white screen. I did some testing, and if you delete the VC plugin using FTP and/or install an older obsolete version of VC (non bundled) the sites backend will work properly.
However, we want both. We want latest version of Jupiter theme and latest version of VC. When I installed Jupiter and their bundled VC plugin on a vanilla test wordpress installation, it worked fine. I believe whats happening is that old jupiter theme, once updated to the new jupiter theme, has some left over stuff that is conflicting with the bundled, modified VC plugin.
My theory is that perhaps I can rebuild a new installation of the site somewhere off server starting from scratch using the newest jupiter version and their modified buncled VC plugin. I am happy to put in the work, but im very concerned about doing this because how am I too transfer all of the "user data" an dby that I mean there are premium membership accounts, purchased music downloads availabel for re-downloading, etc.
Please let me know your thoughts.
