Describe the bug
I can install the mod normally. The corresponding tile on the right side is blank but opens a small window to start the server. When I open "http://localhost:8000/" only a white page appears.

Screenshots

Device Information (please complete the following information):

• OS: Windows
• Browser: Chrome and Brave
• Kerbal Telemetry Version: v2.3
• KSP Version: 1.12.3
• Mod Manager: ckan

Same as above,

Also tried in Edge & IE just in case and same issue.
Also tried with IP & Localhost on both the host and a mobile device and same issue.

I had same problem and fix it.
Check your mod folder installed correctly.

My original path looks like this.
Kerbal Space Program/GameData/Kerbal+Telemetry/Kerbal Telemetry

Mod's path should be Kerbal Space Program/GameData/Kerbal Telemetry
It's space between "Kerbal" and "Telemetry" not plus sign.

Check also "Kerbal Telemetry" folder contains "WebServer", "Texture", "Kerbal Telemetry.dll".

Thanks, that was the issue.
ckan only put the .dll file in the folder.
To fix it I downloaded the mod from the website. I put all files, except the .dll file, in a "Kerbal Telemetry" folder. Then just add these two to the Game Data folder.

Hi guys!

The solution is as suggested by @Ariyn. I am currently back on the development since my workload decreased a bit, and I will be removing the spaces from the names. And I am having an issue with CKAN as well. I am (hopefully) fixing all the errors you guys mentioned. Thank you so much for the help!
