Can't install child beta 3

I just updated the Dashboard 4.1 Beta2 to Beta3 and wanted to update MainWP Child with Beta3 but I receive an error “Installation failed(Error while installing)”. When I update the Beta3 directly on a Child website there is no problem.

I already tried to log out and -in, but this doesn’t change the error.

Hi Leo, thanks for reporting this.

Can you please tell me exact steps how can I duplicate the problem? I tried to install the plugin on my test setup but it worked for me.

I followed the instruction on release page. I did this with the first Beta and this worked fine. In the meantime Wordpress updated to version 5.5.1. Perhaps there is a connection?

Leo do you have iThemes security installed on the MainWP dashboard?

I just tested installing other plugins. When I install a plugin from, the installation works. When I install via upload, I get this error.

Hi Vince,
I don’t use iThemes security.

Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Status → Server, on the top right of the page.

Be sure to use the button like the one below; this button hides all your private information:


Pressing the button auto-copies the report to your clipboard then just paste it in a reply here.

If you have any security software on your main dashboard site, you can try to disable it and see if that resolves your issue. I have that issue with iThemes security and so far there has been no resolution except to disable and then reactivate when finished.

Report looks good. Nothing unusual in there.

Do you get the same error if you disable all plugins except for the MainWP Dashboard on the dashboard site?

Leo you can try to disable “wps hide login” and see if it works.

I disabled all the plugins and nothing changes. I’m planning to restore to a point prior to the beta and verify what does work and what doesn’t. As I seem to be the only one having this problem, the cause probably isn’t within MainWP.

Hi Leo, thanks for letting us now.

If you are able to duplicate the problem again, please let me know and we will look into this.

Also, you may want to look and find which security rule is causing the Server Self-connect to fail:

It is possible that the same security rule is blocking requests from your child sites and cause the process to fail.

Let us know how it goes.

Hi Bogdan!
Just a message to let you know it was my mistake :blush:. I host the server myself and for a couple of weeks I connected to the dashboard with the local IP-adres. When I use the internet IP-adres, like I always did, everything works fine…


Thanks for letting me know. I am happy to see that the problem is solved.
