If widgets or plugins aren’t working as expected, start by ensuring they are compatible with your current CMS version. Plugins often need regular updates to remain compatible, and outdated ones may not function properly. Check if there’s a conflict with other plugins by disabling all plugins, then re-enabling them one by one to identify which one causes the problem. Avoid using too many plugins, as they can slow down your site or create technical conflicts. By keeping plugins updated and removing redundant ones, you can enhance both functionality and site performance.
