Unable to delete/remove snippet. New snippets does not appear. (broken file?)

https://fluentsnippets.com does not link to this page as a channel for support or reporting bugs. If you can improve that.

I have added a code which FluentSnippets is unable to handle (i suggest no one to try that, as it may break your site) https://wordpress.org/support/topic/bug-critical-error-when-certain-code-is-used/ and in order to fix my non working site (as a result of that snippets), i have renamed snippet .php files in /wp-content/fluent-snippet-storage/ by prefixing _ if i remember correct. That helped to make site working again. But from that time, FS in snippets list shows these snippets as active and does not allow deactivating nor deleting these. Even when i create empty .php files for missing snippets or copy different snippets and name them after missing files, or recreate that erroneous files, just changing published to draft in these files, it fails to remove these snippets from the list even the message says that removal succeeded (“Snippet has been deleted successfully”), but unlike in GUI, files was physically removed.

cd public_html;grep -RialE “No google fonts|no-google-fonts” .

…nothing…

index.php file no longer containing that snippets names and newly added snippets are not displayed in admin area (/wp-admin/admin.php?page=fluent-snippets#/).

Exporting snippets and renaming /wp-content/fluent-snippet-storage/ + /wp-content/plugins/easy-code-manager and installing plugin again, does not help, all snippets remains. I am unable to find snippets inside files or database :-S Importing not helped. I can send my index.php or export file, but in private and developers not provided easy to find contact if i am not mistaken.

In short: plugin should always allow user to delete snippet no matter if its PHP file exist and remove it also from GUI, not just file. It should not break the file preventing appearance of a newly added snippets.
