I suspect the message comes from the compatibility check you performed. How did you do that? Which plugin do you use for that?
The plugin I used is PHP Compatibility Checker
Then I would recommend contacting their support forum if you have any questions about the error message: https://ww.wp.xz.cn/support/plugin/plugin-compatibility-checker/
Ok I reply for fixes
Check the project name you entered : If you typed something like My Project #1, change it to my-project-1.
If you didn’t enter a name manually: The plugin might be using your site name as the slug.
- Go to Settings → General in WordPress and check your Site Title — if it has special characters, try simplifying it temporarily to only letters/numbers/dashes, then re-run the scan.
Update or reinstall the plugin
Thanks for your help. I have transferred the issue to the suggested forum
My question still stands – where or how do I find the project name?
Unfortunately, I don’t know what the plugin you are using means by “audit project slug.” If it refers to the plugin slug, then it is, for example, plugin-compatibility-checker for the plugin “PHP Compatibility Checker”. In other words, it is what you see in the URL of the plugin page. Only their support forum can provide you with more detailed information.
