This problem may be a plugin or theme conflict. Please attempt to deactivate all plugins and switch to the default Twenty Twenty-Three theme. If the problem goes away, re-activate them one by one to identify the source of the problem.
If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to deactivate all plugins and change the theme for you while you’re still logged in without affecting normal visitors to your site.
@macmanx Hello!!
I used Healthcheck. Deactivated all plugins – the problem with flash while loading remained. Switched theme do default – problem goes away. So it’s something with the theme… But we used this theme for several month and everything was fine.. What can be done to fix it?
What is the name of the theme you’re using?
Hmm, the theme hasn’t been updated for 5 years, so it was bound to break some time: https://ww.wp.xz.cn/themes/corporate-club/
I recommend taking the opportunity to switch to a newer theme, specifically a block theme, these are all free: https://ww.wp.xz.cn/themes/tags/full-site-editing/
Block themes use the new Site Editor, meaning that how you can modify a theme is now almost limitless without even having to touch CSS: https://ww.wp.xz.cn/documentation/article/site-editor/
There’s also a video tutorial https://learn.ww.wp.xz.cn/tutorial/intro-to-the-site-editor-and-template-editor/ and a full course https://learn.ww.wp.xz.cn/course/simple-site-design-with-full-site-editing/ if you prefer those styles.
In particular, the new default theme, Twenty Twenty-Four, ships with a ton of pre-done templates to get you even closer to what you want before you start customizing it: https://ww.wp.xz.cn/documentation/article/twenty-twenty-four/
@macmanx Thank you!! is there any way to fix this theme?..
If you want to fix your current theme, my only recommendation would be to ask at https://ww.wp.xz.cn/support/theme/corporate-club/ so the theme’s designers and support community can help you with this.
