Just tried installing myself a few minutes ago and getting the same error message when trying to activate it.
As its not been answered in over 1 month now i think its probably best to look for an alternative solution.
Shame, i thought this would be the answer i was looking for.
Hello
yes same here.
I am on the latest version of WordPress 4.7.3
I know this is validated only up to 4.5…
Thanks in advance for an update 🙂
Hi I am unable to install this plugin too and get the following error – The plugin does not have a valid header.
I have also tried to download it from the webpage https://ww.wp.xz.cn/plugins/page-specific-menu-items/ but the install fails.
I have looked online for fix and have consequently checked that the zip file doesn’t contain another zip file.
I am on WordPress version 4.7.4
Can you provide a fix please?
many thanks
