Hello,
I am having a similar problem. I have Virtue as my theme. When I go to appearance, there is an install plugins option and it has the toolkit as a required plugin that I must install but when I try to install it always fails because it says that the destination folder already exists. I know that it had been installed and was working before several months ago. It has not been a huge problem – just my contact form I noticed was not working. But, now my image sliders are not working.
Please advise!
