Settings and Options not working

Hello,

Plugin worked well, but since 2 months ago, i have a huge problem: i cannot access adminimize anymore, i tried from settings and from other link, even i deactivated and reactivated, but still nada.

Here is a link with the outcome, whenever i try to click on it (the plugin works as instructed, as i told it to work 2 months ago, but i cannot enter and change some settings i have made since i cannot access the page)

I mention that
https://ixr.ro/wp-admin/options-general.php?page=adminimize-options

do not load and is given me the error above.

How can i make the plugin load the settings page?

Thanks

The page I need help with: [log in to see the link]
