Solve Elementor Loading Issue
First, go to the PHP INI Editor and increase the memory_limit. Often, when the memory limit is low, the Elementor editor loading gets stuck indefinitely, meaning it hangs on the loading screen.
If the problem persists, enable Safe Mode from the Elementor settings. Once the editor loads properly, disable Safe Mode, and deactivate all plugins except Elementor.
Then, one by one, activate each plugin and check if activating any plugin causes the issue. Disable or find alternative plugins if any plugin is causing the problem.
Browser extensions could also be a cause, so try changing browsers.
Disable theme preloaders and check. X-Frame-Options could also be a reason. If X-Frame-Options is set to DENY on the server, change it to SAMEORIGIN.
If using Cloudflare, temporarily pause it and check. Ensure that both Elementor and Elementor Pro are the same versions. Incompatibility issues could arise if the versions are not compatible.
