    Hi,

    after updating to the latest version I get constant errors and leaving the site very slow … Logs:

    Any chance you can get a trace on that? As it is, I’ve no idea how in the world the regex could ever be empty by the time you hit line 53 of that file. But a trace might shed some light on it.

    Nevermind, I was looking at the wrong line somehow. I know exactly why that error slipped in, and it will be fixed in the next release.
    I actually already fixed it on GitHub without realizing that it was the exact error you were having: https://docs.ewww.io/article/73-update-from-github

    Hi,

    how nice that you have identified the problem!

    The coolest thing about this problem is that it has been able to take a dedicated server out of the air in which I test and pre-upgrade my clients … ??

    Good thing it worked and your plugin is very good, will always be present in the projects of my clients.

    See you later!
