Oh yeah, by the way, if anyone is wondering, to disabled the cache it seems that it works well to add the line force_compile = TRUE to /config/config.ini.php.

Moments later, seeing that everything was working fine, I removed then removed the line that was just added, and still everything seems fine.

Disabling cache did the job for me too. Thanks very much for the support. And great plug-in, by the way. Much appreciated.

Hmm… now there is a second site on the same multi-site where it gives the same error. The two use the same theme, unlike the other sites on the multi-site network. Otherwise the activated plug-ins are the same.

Another possible difference is that in the case of the two sites that don’t work, I initially put the wrong value under “Piwik URL (REST API):” and then corrected it soon after.

I looked in the database, in the wpmulti_X_options tables, for the wp-piwik_global-settings
and
wp-piwik_settings
Comparing one of the ones that gives an error with one that doesn’t, I see only a couple interesting differences in wp-piwik_global-settings:
…”add_tracking_code”;s:1:”1″;s:20:… vs “add_tracking_code”;b:0;s:20:…
Also, only the one that works has at the end : “track_cdnurl”;s:0:””;

Anyhow, I realize that this is maybe not a big deal that the error shows up, as things seem to work fine. Could someone more knowledgeable at least give their opinion as to whether they think this error is likely to point to any future problems or whether it’s not worth checking out further?

The analytics seem to work fine. I see now that I get stats for the website. The error message is still there though. I’m not sure whether I should be concerned or not.
