I have a WP site, I use ASTRA, Starter templates, WooCommerce, WCFM marketplace. Versions of my system: ** WP - 6.4.2, wooC - 8.2.1, PHP - 8.1, MySQL - 10.6.15-MariaDB, HTTPS support - YES** I haven't looked at the page for a while, so page accumulated 18 updates (1 Astra, 17 plugins). Before that everything was working fine - tested many times, made payments, etc. I didn't check the system before the updates (Thought everything should be OK), I made a backup, I did the updates (in a certain order). After doing so, I logged out... after a while I try to log in as administrator - no luck.. I tried to log in as vendor & simple user - I logged in.. I did a restore of the page - as administrator I log in, as vendor I don't log in. I started looking for a solution to this issue: ** I try to log in as a vendor or as a normal user - the page just reloads and the login fields are empty again - no message! If I enter a bad user password - I get a message that the data is bad.** If I try to register a new user, I enter the required data, click register - the page reloads, no message! ** Checking WP Dashboard → Users - no user has been created. Checking the DB (phpMyAdmin), the new user is there - created.** I'm trying to figure out where to look for the error. I tried to check WooCommerce, WCFM settings - everything looks fine. I cleared the browser cache, tried other browsers - same thing.. ** Please help me to find the error & solve it! Or maybe you have encountered something similar and know how to solve this problem? :)** ============================================================= Update: tried to disable all the plugin, except: Woocommerce, WCFM, Elementor - Same Issue!
