CB 2.4.7 breaks Joomla 3.4.6 Site

Greetings all... I am running a Joomla 3.4.6 website and want to install Community Builder. I installed latest CB 2.4.7 and when I add Login module it breaks the website. I can remove the Login module and the site returns to normal. I have tried updating the site to latest Joomla version but that breaks the site and I can't recover it... have to reinstall a backup of the site.

I understand that CB version 2.0.15 works well with Joomla 3.4.6 and I am trying to locate this older version to install on my website. Can anyone tell me where to find CB 2.0.15?

Appreciate any help you can give with this issue.

Why are you using Joomla 3.4.6? Please update to 3.9.24. Your install is significantly out of date. There has been several vulnerability fixes in Joomla since 3.4.6. We do not provide 2.0.15 anymore. We only provide releases so far back. The CB Login Module breaking your site also isn't very descriptive; it's breaking your site how exactly?

Hi krileon... Thanks for responding. I'm using 3.4.6 because when I update to 3.9.24 my site front end and back end are no longer accessible. I get white screens with error messages on both. I would like to update but I haven't been able to make it work... When I add a CB Login module to the site the front end is no longer accessible, it turns white with a blue button that says "Go Back Home". and the button doesn't work. I included a screen shot of the what appears in place of the website. In the Chrome browser tab it says 0 - Error: 0.

Any suggestions as to what causes this and how I might correct the problem? I would be happy to provide any further information that would help.

Then you got much bigger problems than just updating CB. Probably a 3rd party extension loading through a Joomla system plugin as that'd be the only way it can globally impact everything. Check your server error logs to see if there's any fatal errors.
