Thank you so much for responding so quickly. Each day that this goes on, I’m potentially losing clients. I really appreciate your help. To answer your questions, I’ve re-enabled PayPal Pro, which I do have and which I do pay for monthly. I have checked my API credentials for extra spaces and even de-activated the plugin, cleared out the credentials, re-inputted them and even gotten new ones. I’ve also installed the plugin “Real Simple SSL” to make sure my SSL is installed/initiated correctly. I’ve tried contacted my host, who was the one who suggested I walk through the “whynopadlock.com” site, which I did (and corrected all the problems). I’m sure it’s something small that I’m/we’re overlooking and I really appreciate the help!
