Problem: If you're upgrading your site to PHP 8.3 from PHP 7.4 and encounter a login loop when WPML Multilingual CMS and Share Buttons by AddThis plugins are both activated, this might be due to a conflict between these plugins under PHP 8.3. This issue results in an inline JavaScript block within WPML's script growing uncontrollably, causing the site to run out of memory. Solution: We recommend deactivating the Share Buttons by AddThis plugin or replacing it with another plugin that is compatible with WPML. You can find a list of WPML-compatible plugins here.
