I am troubleshooting a WordPress site and often when loading a page, as a visitor or admin, an error box pops up with that says "Conflict with another plugin which overwrites jQuery". After researching I found that WordPress version 5.5 does not work well with older versions of themes and plugins. However after updating or deactivating any plugins that caused errors, the error popup persists. I also found a plugin called "Enable jQuery Migrate Helper" that was supposed to suppress the error for website users but this does not help as well. How would I go about solving this problem?
