Hello Guys,
Spent months with this problem (tickets with Woocommerce, long e-mails, sharing logs, talking to my hosting provider, so much effort). After a while I created a new subdomain (you should be able to do this from your webhosting provider’s controll center or from your cpanel) and installed a fresh WordPress with a fresh Woocommerce on it. Nothing else, no other plugins. Still, it showed me the error message. Then, sometimes it worked, however, other times I got the error message.
Somebody wrote that maybe my hosting service (the provider of the space where you install WordPress) is not ‘good’ enough. I upgraded my service at the hosting provider. Surprisingly the situation got better, however, still I got the error message quite often. And, if there are problems with Woo before even starting to setup my store, how would I dare to start investing my time and resources into start building my store? More problems may occur later..
So, at that point I tried the whole thing on my other domain which was sitting with a different provider (with a slightly more expensive package). I created a subdomain there, installed Wocommerce, and, surprise, everything worked well, no error message at all! So relieved, I am.
I hope this helps for you folks.
By the way, at the moment I am migrating my whole domain (the one I want to build the store on) to this other, apparently better, provider. It is said that practically no disruption should be experienced due to the migration, should be done within 24 hours with some documentation, and there is no need to even contact the previous provider. Please note that I cannot guarantee for you that you can do this so seemlessly with your provider as written here. This is rather some kind of encouragement to contact the new, desired provider and get guidance how to do the migration. Good luck!
