Background of the issue:
I'm experiencing an issue with activating the OTGS Installer on my development site. Although the installer shows as activated in the plugin list, it does not function properly. Link to a page where the issue can be seen: hidden link
Symptoms:
The plugin appears as activated, but it does not work as expected. I am unable to install or update WPML-related plugins.
Questions:
Why does the OTGS Installer show as activated but not function properly?
How can I resolve the issue of being unable to install or update WPML plugins?
Thank you for contacting WPML Support. This type of issue usually happens when the WPML is not registered properly on your development site. Could you please delete the existing site key and create a new one by following below steps:
1. Login to your WPML.org account >> Go to the Sites page: https://wpml.org/account/sites/
2. Delete the existing site key (if it exists).
3. Login to your site and go to the Dashboard >> Plugins >> Add new > Commercial tab and click the Unregister WPML from this site link if that link exists.
4. Then click the Register WPML link.
5. Click the Get a key for this site link.
6 It will generate the Key for your site.
7. Copy the key, and paste it back into the input box, and press the Register button.
8. Next, take a backup of your site and try to install/update WPML plugins.
Please let me know if this resolves the issue or if you need further assistance with this issue.
