Which plugin, in particular?
What do you mean by “have jQuery update”?
Many plugins do not delete their data unless/until you use the “Delete” option to delete the plugin from the filesystem. If you deactivated the plugin and then deleted it using FTP/SSH, then the only way to remove the plugin’s data is to delete the data manually from the database and/or filesystem.
If you used the “Delete” option and the plugin did not remove all its data, then that’s IMO a bug in the plugin, and it should be reported to the plugin’s author.
Hi @sterndata
When i update my wordpress to the latest version it actually broke some parts of the features of the website. i think that maybe i install plugins before but after i uninstall maybe some data from the plugins are still left that causes the error. because i keep checking the internet and they just say they usually deactivate the optimization plugin which i also did but nothing happens. so i think maybe one of the optimization plugin i used to install before causing the problem.
What problem(s) are you having? What broke?
hi @diondesigns
but why the other plugins after i delete the effects are still in the website which causes some problems to the website. the problem is i can no longer trace the other plugins that i install
hi @sterndata
some sliders that use jquery, even if i updated the sliders in the latest version i still encounter the issues.
Please try installing https://ww.wp.xz.cn/plugins/enable-jquery-migrate-helper/ to see if that fixes the issue.
If the plugin helps, please contact the developers of the plugins or themes noted in its admin messages.
Hi @sterndata
I already installed the plugin but it doesn’t help me fix the problem.
I also have another website that use the same plugin but doesn’t encounter any problems.
That’s why I think that probably the cause of the error is something I installed before but the data remains somewhere in the files or database but I cannot trace anymore.
1. What plugin?
2. What problem(s) are you having?
3. What errors do you see?
hi @sterndata
I use slider revolution for the sliders which doesn’t load in the front end in the client side even if I clear the cache in the website but it appears in my end where i logged in into my admin account.
The other problem i encounter is the other page don’t load properly where it loads and appear as no css then load as completely blank page even no matter how much i reload i encounter the problem unless i clear cache. but even if i clear the cache some pages still encounter that blank page problem.
Because you’re using a commercial plugin, Slider Revolution, please use their official support channel. We feel they are best equipped to support their products.

Commercial products are not supported in these forums.
with respect to a blank page, errors like this are logged. Check the error log on your server. If you can’t find the log, please contact your host.
Meantime, enable wp_debug and wp_debug_log and after an error, look at wp-content/debug.log to see if anything gets logged there. https://ww.wp.xz.cn/support/article/debugging-in-wordpress/
You can also try this: Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
If you cannot access wp-admin, there are other ways to deactivate plugins.
