Hi @brandondove

Sorry about the trouble. It seems when updating the plugin, some old files weren’t removed that should have been removed. Are you updating the plugin manually or are you using the WordPress plugin updater in the WordPress Admin UI?

Basically, this can be likely fixed eg by removing the following file:

wp-content/plugins/matomo/app/plugins/VisitorInterest/Columns/VisitsByDaysSinceLastVisit.php

You might also want to check if other ones need to be removed like

wp-content/plugins/matomo/app/plugins/DevicePlugins/Columns/PluginDirector.php
wp-content/plugins/matomo/app/plugins/DevicePlugins/Columns/PluginGears.php

Do those files exist in your installation? And if so, can you try to remove them?

The information might be still cached and you might need to go to “WP Admin -> Matomo Analytics -> Diagnostics -> Troubleshooting” and click on the “clear cache” button but I think it might not be needed.

Thanks for all this @timherinckx . Very appreciated. I just downloaded the WP 5.6 release (I’m already on a newer version) and indeed it is marked as version 5.6. Glad I waited for your results 🙂 I’ve done some more testing with different version comparisons and justed the original pull request and a fix will be included in the next release. Thanks again for all your help.

@matheka-jnr I’ll mark this issue as resolved for now as I haven’t heard from you in a while. If you still experience this issue feel free to comment any time and we will follow up. It might be also worth updating to our latest release which may have fixed the issue.

Hi @nam1962 is your Matomo for WordPress now running on a different server or the same server as previously Matomo On-Premise? If it is a different server, is it the same kind of server or maybe even on a different hoster?

I’ve installed so far the same plugins (the plugins that are available through WordPress plugins directory) and it loads fast to me.

Hi @nam1962

I just had a look at your site and I can see the important load metric is around 2seconds and not delayed by Matomo which is great. I can see how your Matomo request is unusually slow. Did you have previously your Matomo instance running on the same server and there it was faster? Or is Matomo now running on a different server?

Any chance you could also post your system report here which should be automatically anonymised? https://matomo.org/faq/wordpress/how-do-i-find-and-copy-the-system-report-in-matomo-for-wordpress/

Thanks for that @nam1962

Hi @timherinckx When you uninstall the plugin, by default it won’t wipe the data but it will wipe the config file which should be automatically recreated on install. The safest way be though to manually remove the plugin from the directory directly and then either uploading it again through the WP upload feature or manually uploading the extracted zip file. Does this help?

Thanks for this @timherinckx very appreciated. It seems when I updated to 5.6 WP did not delete the older files which is how I did not notice it. I’ve now manually removed these files and noticed the Matomo UI still works though even the files don’t exist. Can you confirm this?

I’ve prepared a fix for this in https://github.com/matomo-org/wp-matomo/pull/408/files

If you wanted to test it, you could replace the content of the file wp-content/plugins/matomo/plugins/WordPress/WpAssetManager.php with this content: https://raw.githubusercontent.com/matomo-org/wp-matomo/70ca674806c8fe3acd3d188b39d019033641cd01/plugins/WordPress/WpAssetManager.php

Thanks again for bringing this up and creating the WP issue.
