does not have header

Hey,

Delete the plugin and install it again.

peace,
Rolf

the same problem
no luck after reinstall

I found out that I could install it by going to the Plugins list and clicking Activate there.

Hey ingere,

Not sure what causes this, but I’m glad you found a workaround!

Thanks for the feedback.

peace,
Rolf

I faced the same problem. I cleared wp-rocket’s cache and that seemed to fix the problem.

I found the following error during activation.

The plugin does not have a valid header.

SOLVED

I just optimized my DB after that, i tried to activate this and suddenly its activated ??

Confirmed – I could activate it only from the Installed Plugins page.
