<!-- WP Super Cache is installed but broken. The constant WPCACHEHOME must be set in the file wp-config.php and point at the WP Super Cache plugin directory. -->

Deactivate that.

Where do you see this “WP Super Cache” causing the problem? I do not see a WP Super Cache in my list of plugins. I did have a WP Fastest Cache plugin on my site but that was already deactived, I have since deleted the entire plugin. I noticed this caused issues in the past.

Checkout on my site was working fine as of 8/19/15 till I upgraded the newest version of woocommerce

I do see some old “cache” folders and files in my wp-content folder. Could these be some left over files? Is there something left over that is interfering with my checkout? How do I fix this. Thanks so much for the help so far.

Delete any left over cache folders, and deactivate any cache. I saw this appended to the ajax responses, hence it was broken.

ok deleting cache folder in ftp, how do i deactivate any remaining cache? is it anything with my php script too?

deleting the cache folder did not help it seems, now the checkout page looks even worse. It lost its formatting and the “spinning wheel” is still happening ??

after doing what you said, deleting the cache and plug in files the formatting of the whole site is off. on the flip side checkout appears to be working but everything is all strecthed out and seems like the css is broken

Deleting cache won’t do that. Are you sure there are not other caching/minify scripts active?

not that i know of. could it be my theme was pointing to info in the cache and it lost some formatting? the site is working fine except its lost all the formatting that I believe is controlled by css.

i think i messed up my style.css file in the child theme last night and pasted into that file the “Customer processing order email” script.

and so when i deleted the cache its no longer pointed to the right thing anymore and is corrupt. darn and i dont have a backup of the style.css

i hope i can put a generic one in

Hope you find a backup. At least the OP is solved ??
