To rule out the possibility of a plugin or theme conflict, please deactivate all your plugins (besides Elementor and Elementor Pro) and then update to the newest version If it solves the issue reactivate them one by one to find the culprit. If it didn’t help, switch your theme (temporarily) to a default WP theme such as Twenty Nineteen and see if it makes any difference.
Also, this could happen due to our Elementor performance experiments you can try to deactivate them. To deactivate them you can go to Elementor > settings > features
Performance features currently in the experimental stage are:
- Optimized DOM Output -This experiment is designed to improve performance by decreasing the number of wrapper elements present in the HTML generated by Elementor.
- Improved Asset Loading – Should improve page speed by only loading the functionalities needed by that page. This experiment reduces the amount of code loaded by default, which translates to significantly faster page load times and better page speed scores.
- Improved CSS Loading – An experiment that only loads the CSS of widgets on a page once, in order to prevent multiple requests to the server. With this experiment, CSS files are loaded as inline style tags.
- Inline Font Icons – This experiment renders icons as SVGs without loading the Font-Awesome and eicons libraries. Since SVGs are vector-based images which are rendered using the browser’s engine, they do not increase server requests which improves performance
