Error when i try to launch page

If you are confident the issue is the slider plugin you should start by uninstalling that and seeing if the issue is resolved. If that doesn’t resolve the issue either a) it isn’t actually the issue, or b) it messed something up in a way that will be easiest fixed by restoring a backup or moving to a fresh WordPress install.

If you have access to wp-config.php you can go in there and turn on debug mode, which might help.

Hi @mabo77 ,

Please follow the below step to resolve the issue,

1) First take the full backup of your website.
2) Disable plugin one by one. Go to wp-content/plugins/name_of_plugin just rename the plugin one by one and check website is accessible or not. Rename plugins_old back to plugins after resolving the issue.
3) Clear Browser Cache and Cookies.
4) Check wp-config.php for Errors: Make value true for “WP_DEBUG”
5) Check for JavaScript Errors (Browser Console)
6) Increase PHP Memory Limit: (Add in wp-config.php file)

define( 'WP_MEMORY_LIMIT', '256M' );

7) Manually Update WordPress (Core Files):
– Download latest version of WordPress from https://ww.wp.xz.cn/ website.
– First rename the wp-admin and wp-oncludes folder and upload new one. Then upload file with name wp- in root folder except wp-config.php file.

8) Rename the activated theme and revert it.

Please perform all above step carefully one by one.

Thanks.
