Can't install .zip plugins

When I try to install a plugin from a .zip file in the MainWP dashboard, I get this error:

Installation failed(PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature)

I can install the same plugin directly on the child site through the site admin dashboard, but the same plugin will not install to any child site via the MainWP dashboard.

Any ideas what might be causing this error? The sites are in multiple hosting environments with different providers.

Thanks in advance for your help!

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.

Hi Bogdan, below is the report after attempting to install iThemes Security Pro from .zip.

Thanks!

Do you get the same error if you deactivate the iThemes Security plugin on the site?

Yes, same error: Installation failed(PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature)

Strange. Can you try one more test and try to upload&install some other plugin, for example, download Akismet from WP.org and see how it goes?

Same error: Installation failed(PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature)

Thanks for checking that.

Can you send me temporary access to your MainWP Dashboard (via Private message) so I can check this further?

I just tried to duplicate the issue, and I could but as soon as I deactivate the iThemes Security plugin on your dashboard site, it works normally.

Can you retest that?

Aha! Thank you, Bogdan!

When you originally suggested deactivating iThemes Sec I thought you meant on the site I was trying to install it on, not my MainWP dashboard. After deactivating on the MWP dash and trying to upload and install iThemes Sec Pro, it worked as it should.

Mystery solved, thanks once again!
