Hello,
Sorry but I cannot accept your approach. I have 18 plugins on my WordPress website and i do not have any such problems with other plugins. I think your plugin should be simply more versatile and adjustable to various codes and options, not the other way round.
I have been using the free version for several years. However last updates (after version 2.9.2) hanged my website and I had to restore it from backups. I do not know what happening is. Maybe someone knows the solution to the problem for which I will be grateful.
