Contact with your purchase item author hope they will helped!


The author’s FB page told me to visit here for a solution. Finished a WordPress update to v.5.5 and then the Curly Themes Equestrian site told me there was a new version. CRASH city since. Been to the well for the theme and find myself in a do loop of marketing! Just wondered if a user could help me back to the old version!
