I'm sorry, I'm using Mercury light and I it's been fine for a while but recently whenever I go to customize my theme I keep getting the message "your custom html theme seems to be invalid" pop up, and it tries to recover the theme I was using beforehand. I haven't messed with the theme, I don't know what triggered it, and I've tried reinstalling. Any ideas?
Hello,
I've gotten this message before too, and a couple of other theme makers have encountered it as well. I don't think we've come across a solid solution yet, but apparently changing your theme too many times in a day causes the message to pop up.
Reinstalling the theme worked for me, deleting cookies worked for someone else, and deleting the "DOCTYPE" code at the top of the theme code worked for another person.
If you come across something that works for you, lemme know.
