My Theme is Not Listed

The plugin gets the list of themes directly from WordPress. Therefore your theme is one of those listed, or it is not installed on the site properly.

Please do not assume my level of WP knowledge.

We develop WP themes for our clients. It’s a custom theme and installed properly.

Okay, then you tell me why it’s not in the list.

The dropdown comes from the list returned by wp_get_themes(). So, is your theme listed in the response from that built in WordPress function?

I had the same problem…
Check if you have commented line “/* Theme Name:” at the start of your style.css file found in root of your custom theme folder.

Realistically, if the Theme’s style header is malformed to the point that the WordPress functions can’t see it as a valid theme, then I’m not sure how you would activate it for the active theme either.

If you have an example or a way for me to reproduce the problem, then I’m happy to figure out how to fix it, but I don’t have any idea on how to make this error occur.
