Hi, my magento website is on a shared server. Suddenly today the URLS (SEO friendly) in subcategories stopped resolving. Querying this with the hosting company, they told me that they had upgraded their litespeed version on the server to v5.3.6 which coincided with the errors. They have promptly rolled back to the previous litespeed version 5.2.2 which has fixed the issue. However, this is to give me some breathing space to get it properly resolved. Thir advice was to check my installation so it works with the newer version. Do you have any insight into what I should check first? Advice greatly appreciated. Thanks v much.
