Messages and what to do
| Message | What to do |
|---|---|
| "Server is missing the Zip extension; cannot install packages." | Ask your host to switch on PHP's zip extension, then try again. |
| "Install directory is not writable." | PHP must be able to write to plugins/ (add-ons) or assets/themes/ (themes). See Folders your store must be able to write. |
| "… needs Kernel 1.x or later; this site runs 1.y. Update the site from Software update first." | The add-on was made for a newer core. Update the core in Appearance Software update, then install the add-on again. |
| "… needs another plugin x or later (this site has y). Update it from Plugins first." | Update the plugin it names, then try again. Themes ask for this when they style a plugin's pages. |
| "… is older than this site supports; it needs x or later. Install a newer version of it instead." | Your core is newer than this copy of the add-on. Get its latest version with Check for Updates. |
| "The package is not signed, so it was not installed." / "…failed its signature check…" / "…signed with a key this site does not trust." | Packages from the licence server are signed, and a package that fails the check is never installed. Download it again with Check for Updates; don't install a copy that was opened and changed. If it keeps failing, email us the message. |
| "This store uses virtual coins only, so "…", which moves real money, can't be switched on." | Rewards (coins-only) stores can't run payment gateways, payouts or other add-ons that move money. This is by design. |
| "A plugin named "…" is already installed." | Update it from Plugins instead of installing it again. |
| "This plugin contains code that can run commands or is obfuscated" | The message lists the files. Review them, and only tick "install anyway" if you trust where the plugin came from. |
| "Could not move the plugin into place; the installed version was kept." | Usually a full disk or a permissions change. Free some space or fix the folder's permissions, then try again. |
An update shows but won't install
Check for Updates on Plugins and Appearance Themes offers the newest version your core can run. When an even newer one needs a newer core, it's shown so you know to update the site, but it's never installed, not even with Update all. Update the core first, then check again.
A strip warns about a plugin or theme
A strip at the top of your admin pages warns when something switched on can't fully run: a plugin older than your core supports, a plugin whose required core is newer (usually after rolling back), a plugin that failed while loading, or a theme that needs a newer core or plugin. It keeps running where it can. Update what the strip names. The Plugins page shows the full details.
An add-on you own isn't offered
- Your store downloads add-ons from the licence server, so it needs outgoing HTTPS. If it can't connect, see Licence and activation problems.
- Bought add-ons show on the Owned tab of the Add-ons page, with buttons to install and switch them on. If the licence server refuses your store, that page links to the licence page to verify it.
