That's strange I get the same error from a dev website hosted with MAMP PRO
I am able to update all extensions including CB version 2.6.4 with the manage/extensions/update menu (just updated), but when going to CB/install from web I get Failed to load install from web. Please reload to retry.
I'd like to keep dev and live server updated with this function.
Can you help in debugging what's going on ? I have no errors in console
1. Did you create a specific site key in your Joomlapolis user profile, and enter it in the CB Configuration ?
2. If yes, then right-click on page, click inspect, go to "Network" tab, and then reload the page. You should then see the ajax calls for updating the packages list, as well as a possible error-code, like a browser plugin that stopped the request. Or a very strict browser setting. What do you see there ?
Yes a specific site key exists in the profile and is entered in config for this local dev site
Strangely I cannot see any request or ajax call to joomlapolis or other website in the network tab. With full debug on I don't have any errors and install from web stays empty
When trying extensions/update I get all the packages which need to be updated and can correctly install the updates but CB packages does not appear nowhere, neither in CB plugin update menu nor in the extensions/update
