I run a magento website on version 126.96.36.199 and recently went to install the new security patch 10266.
However, after doing so I have experienced quite a few problems. The first problem I noticed was that I was unable to remove products from the Minicart, I was getting an error message instructing me to try refreshing the page.
Secondly, during checking out it asks you to log in even if you are already logged in and also when you add a zip code for a postage estimate it does not update the total.
I decided to revert the patch but for some reason I am still having issues.
I read somewhere that this could be related to file permissions, so downloaded and ran magento-cleanup.php from Github... but still seem to have the issues.
Has anybody else experienced similar problems or have any advice?
Any help would be appreciated.
Thanks in advance.
