Just thought I would mention this here while I start troubleshooting to see what is causing the issue.
On more than one site, I can't upload a new theme file via the theme upload. The resulting page after trying to upload is a "Site can't be reached" with an ERR_CONNECTION_CLOSED error.
When reviewing the error log from within the Cyberpanel admin, I get this ...
Failed to obtain or reinitialize VMemBuf.
Would this be something I should submit a ticket for, or could there be a simple solution I haven't found yet ;-)
Thanks ... Scott
