Installation failed

Hi,

Never faced this.
Can you post any details?
Website URL?
What kind of customization has been done?
Are you facing this with other plugins as well?

Thomas

First time now with a plugin. The site is panza.fi

Would you be so kind and do the following:

1.) delete wp-content/plugins/duracelltomi-google-tag-manager/
2.) try to install my plugin again
3.) copy/paste the full error message that you see, not just “no header found”

I deleted the plugin folder now from the server and tried to install and activate it again. “The plugin does not have a valid header.”
