Thanks for feedback! I always want to hear about issues... even if I don't know the cause.
In this case, I haven't had any problems with the site, personally, nor have I received any server errors or hosting warnings. The site software is updated to the current version.
It seems strange that the problem is resolved when you clear your browser history and reboot your computer. Typically those kinds of glitches would indicate that I am changing the site software and your browser cache is inconsistent with the new site software. Except I haven't done anything to the site in at least 30 days.
Let me know if you continue to have problems!
