So, if I disable OtterBlocks, the calendar works, but the site looks like something from the 1990s.
If I have to choose between OtterBlocks (nice site) but no Event Calendar AND Event Calendar but ugly site, I fear I will have to find a replacement for Event Calendar Pro.
I’ve been caught between two vendors before: I’m sure you will blame it on OEvent Calendar, and they will blame it on you. SIGH
