weathermap disabled - Uncaught Error: Class "index" not found

[esanders83]

Hello,
I'm running the following:

• Ubuntu 22.04.1 LTS (jammy)
• PHP 8.1.2 (apt stock)
• NGINX 1.18 (apt stock)
• Cacti 1.3.0(git clone -> dev eaefda08)

I installed weathermap from git clone (https://github.com/Cacti/plugin_weathermap.git), changed permissions, and I enabled/install the plugin. Once I start trying to add a map Weathermap crashes and the cacti.log shows:

2023-01-17 14:40:07 - ERROR PHP WARNING in  Plugin 'weathermap': Cannot modify header information - headers already sent by (output started at /var/www/html/cacti/lib/functions.php:1543) in file: /var/www/html/cacti/plugins/weathermap/lib/datasources/index.php  on line: 42

What else I can provide to help troubleshoot this?

Thank you!

Did you install this over a pre-existing install of Weathermap? If so, move the lib folder out of the way, and copy the lib folder fresh from the cacti repo version.

Hello,
This was a fresh install of Cacti and weathermap. Sorry, I accidentally closed this incident😞

Okay, now I know why you are experiencing this as well as others fixing now. Helps reading the tickets on a PC and not one your phone. Old age and no glasses ;)

Try out this patch as it may take a day or two to get merged.

Hello again,
I applied the patch and it worked without any errors or reverting to disabled plugin.

Thank you for your help on this!

Updated the formatting in the original post, the solution looks good.
