    We’re getting an error message coming up on quite a number of our sites, all running up to date:

    Warning: mkdir(): File exists in *****/wp-content/plugins/comet-cache/src/includes/traits/Plugin/InstallUtils.php on line 361

    It appears that it’s not a constant thing, and that the error message itself was cached. Logging in and clearing the cache cleared it for now.

    I do run a security plugin that locks down a lot file writing permissions (iThemes Security), could that be causing a conflict?

  • @nathan-adams Which version of Comet Cache are you running? We implemented a fix for that issue in the latest release (v160917); see this GitHub issue.

    the error message itself was cached.

    Hmm, that seems unlikely. Did you actually inspect the cache file itself to see if that error message appeared in the cache file?

    If you’re already running the latest version of Comet Cache (v160917), then I would suspect iThemes Security, yes. We’ve heard reports of all sorts of strange issues caused by iThemes Security, across several of our plugins, not just Comet Cache. In general, we recommend Wordfence, as that seems to be more compatible with other plugins.

    Hi Raam,

    I’m running 160917 on all of our sites.

    The error has reappeared on one of our sites, and the error is definitely being cached. I’ve opened up wp-content/cache/comet-cache/cache/http/site-name/index.html and it’s there on the second line.

    I’ve been running both iThemes Security and Comet Cache for quite some time now, and it’s only been recently that this issue has come up.

    @nathan-adams In that case it sounds like iThemes Security might be causing this problem. Comet Cache cleans up things on its own and recreates things all the time in the cache directory, and if iThemes Security is somehow preventing the deletion of a directory that Comet Cache is trying to clean up and then recreate, you could see errors like that.

    If possible, can you exclude the wp-content/cache/ directory from iThemes Security altogether?
