Troubleshooting SlimStat Pro License Activation
Applies to SlimStat 6.0.0 and SlimStat Pro 3.0.0 · checked
If Pro does not activate, first confirm SlimStat Free 6+ and SlimStat Pro 3 are both installed and active. Then open SlimStat → Settings → License, enter your key and save. Check the status displayed beside the key.
Check the key and the site
Sign in to your account and check your license, subscription and site allocation. Copy the key without extra spaces. A moved site, a staging domain or an exhausted site allowance can require updating the allocation. Contact support if you cannot change it in your account.
| What you see | What to check |
|---|---|
| No License tab | Both plugins are active; Free is at least 6.0.0; your account can access SlimStat settings |
| Inactive or invalid key | Key, license status and licensed domain in your account |
| Activation works on one site only | Your plan’s site allowance and each site’s allocation |
| Connection error or timeout | Outbound HTTPS, DNS and certificate validation on your host |
| No Pro update offered | Active license, a newer available version, and the WordPress update check. A Pro release that needs a newer Free than the one installed is held back until you update Free |
Check the server connection
Pro 3 uses the license and update API at https://my.wp-slimstat.com. Ask your host to check outbound HTTPS to this hostname. Do not disable TLS certificate verification. A browser reaching the website does not prove your WordPress server can reach it.
WordPress Tools → Site Health can help identify HTTP and configuration problems. Both plugins require PHP 7.4+ and WordPress 5.6+. Use the official ZIP from your account; renamed or incomplete plugin folders can interfere with updates.
Update without deleting your analytics
Back up first, then upload the current Pro ZIP through Plugins → Add New Plugin → Upload Plugin and follow WordPress’s replacement flow. Keep Free active. Avoid deleting Free as a license troubleshooting step: uninstall behavior depends on your data-deletion setting.
Send a useful support request
Include Free and Pro versions, WordPress and PHP versions, the exact error text, and whether the site recently changed domain. Use private support for account issues. Do not post license keys, database passwords or visitor data in public tickets.
