Custom Plugin causes "Look And Feel" Configuration Page not fully loaded

Question

We recently migrated from JIRA 6.x to 7.x

After the migration we noted that the general "Look And Feel" Configuration Page does not correctly show up. The properties for Colos, Gadget Colors and Date/Time Fromats are not displayed anymore.

We found out that disabling a certain custom plugin solved this issue. I cannot read any valueable information from the logs while enabling or disabling the plugin.

The plugin does not interact with the configuration page, so for me it's to understand this

Do you have an idea what could cause such a behavior?

Hi @Matthias Mueller

I Think Jira is trying to make a call to your server which is probably running on HTTPS, but if you have a self signed certificate then it'll fail to validate the certificate. When  plugin is in disabled  And Check It will Go to the call to https

Thanks @PVS  But does this explain, why it works if the plugin is in disabled state?

Hi @Matthias Mueller

The "Auto Look and Feel" functionality uses the defined Base URL for reference.  An invalid URL or an URL that cannot be access results in error.   See bug report here:

https://jira.atlassian.com/browse/JRASERVER-33340

Check the Base URL

* JIRA Administration > System > General Configuration > Base URL
* Ensure that the defined URL is correct and valid
* If not update it to the proper URL

If using SSL and Base URL is correct

* In this case, you will be SSL related errors within the logs
* Double check your SSL configurations and ensure that you have a certificate properly installed into the Java environment.

Thanks ,
