(SOLVED – it was the plugin “jQuery Updater” that did it. I stopped that and everything worked fine again. sorry.
i just updated to 4.6.3.1 and now my 2 masonry galleries and the timeline not showing at all – BUT only on PC, not on the iphone. (both IE and chrome) It does NOT depend on being in a color section or in a footer.
For some reason i can not even delete the theme and install a new version – NOT even 4.4.1 – it will not solve this problem.
