Thank you Lester: solved.
Have the same issue
‘The plugin does not have a valid header.’
Unless its here in WP > Trusted Source – will not be DL from anywhere else.
When its fixed, I will back then…
Continue to have same problem on others website with the original file ‘The plugin does not have a valid header.’
Again and Again, please fix.
Can you re-install the plugin again? I have fixed it and re-tag it at 1.0.9.
Just go to https://ww.wp.xz.cn/plugins/wp-sweep/, Download 1.0.9, and overwrite the files on your server.
Also for the error, https://ww.wp.xz.cn/support/topic/the-plugin-does-not-have-a-valid-header-85/?replies=9, just de-activate it and activate it again, might be due to a WP cache.
The plugin does not have a valid header.
Same error on new version too, i have no Wp-cache
The error appear only when i click “Activate”
if i coming back in the browser re-active the plugin on plugin page the problem disappear.
I got the same “no valid header” too after activating but it works after I deactivated it and then activated it.
