If you have installed Chatstack and the live chat popup window is showing a blank chat window then we recommend the following troubleshooting steps.

• Check that the /livehelp/templates_c/ directory exists. If this directory doesn’t exist then please create it.
• If the chat window is still blank then make the /livehelp/templates_c/ directory writable. We recommend that you try the following permissions in this order 755, 775 and 777. Windows Servers should have Full Control permissions for the Internet Guest Account

The /livehelp/templates_c/ directory should be writable so that the Chatstack templates can be created. This issue will only affect Chatstack installations v3.90 and above.

Please note: If you are using Security-Enhanced Linux (SELinux) then you may also need to setup allow_httpd_anon_write to 1. You can do this by running the command setsebool -P allow_httpd_anon_write 1
