The plugin does not have a valid header

mrinkman –

I will take a look and try to reproduce, can you tell me what version of WordPress you are using and also what other plugins you have installed?

Thanks.

same issue here.

“not a valid header”

divi theme

plugins
css hero
divi booster
divi module editor
duplicator
elegant themes updater
force regenerate thumbnails
google analytics dashboard for wp
google seo pressor snippet plugin
jetpack
microthemer
polylang
timeline express pro
updraftplus
w3 total cache

I’m also having the same issue when I try to install. I’m using a divi theme (latest version) and wordpress version 4.2.2. I’m using these plugins:

Black Studio TinyMCE
Church Pack Pro
Elegant Themes Updater
Gravity Forms
Sermon Manager
White Label CMS
WP Edit

I did a little further investigation and found that the plugin installs, but when I try to activate right after the installation (I am asked immediately after the plugin installs), it gives me the invalid header error. If I go into my dashboard plugins screen, the plugin has installed and if I click on activate in there, it activates fine.

Thanks for the details. Must be an issue on install, I will look into it and correct.

Thanks Adam – This is a great plugin.

I looked into this a bit more. I was not able to reproduce the issue with a stock WordPress 4.2.2 install and default theme active. I did, however, notice an issue where the 0.6.3 release contained a duplicate of the plugin code in a subfolder. This may have been causing the activation errors, although I can’t be certain as I could not reproduce.

I’m marking this as resolved. Thanks for bringing up the issue.
