I was thinking I would install a clean copy of Invision on my computer and then import the clean theme tables, to replace the one in my current database, as I just can not find any way to get rid of the Affinity and test theme. I did edit the test them to remove the parent option. I shouldn't have deleted the main default theme either. I was thinking the 4.3 was the newest version of the default theme. I just seem to be making a mess of things.
I no longer use any theme except the 4.3 default one. I did add in my custom css from my Affinity theme to the default theme and it does not seem to be what is causing the problem.
Thanks so very much for taking the time to answer my question, I greatly appreciate your doing so.
