I just purchased my plugin update to Weaver Xtreme Plus. Weaver’s download page gave me the file weaver-extreme.4.4.8.zip. I tried to upload from the WordPress Plugins – Add New page. Received error message: “The package could not be installed. No valid plugins were found. Plugin installation failed.”
My Plugins – Installed Plugins page shows that I have already installed Weaver Xtreme Plus version 4.0 and Weaver Xtreme Theme Support version 5.0. I went to Appearance – Weaver Xtreme Admin and Xtreme Plus which verified my license key.
So it seems that my update 4.4.8 did not install and I don’t know why.
FYI the theme I am using is a Child Theme weaver-xtreme-child-0.
weaver-extreme.4.4.8.zip is the basic free theme, not the Plus Plugin.
If you have the Plus plugin Already installed, Then I don’t understand what you are trying to do, you do not need to reinstall anything. Renewing the subscription will make the installed plugin automatically check for update when some are available
If you need to update to the latest Version of the theme, you can you that from WordPress.org from your dashboard.
Your Dashboard > update would tell you if you need to update the theme, and let you do it from here.
