Maybe you are not formatting the CSV correctly? Please show a sample of a file you are using.
I don’t know about @ajezouit, but for me the “The plugin does not have a valid header.” comes when trying to install/activate your plugin.
@bamajr, try installing via FTP.
@ulrich Sossou – Actually, I found when a person gets this error, during installation or activation of your plugin, a person can just type in:
http://DOMAIN.TLD/wp-admin/plugins.php
or
http://DOMAIN.TLD/wp-admin/
or
any other link back to the admin panel and look at the installed plugins, it shows up as installed and/or activated. At this point, it seems to work fine.
However, I find it odd how I have several sites running 20 or more plugins, and have never experienced this error with any other plugin. However, I experienced this same issue, with this plugin, an all the websites I tried it on and I experienced it after installing, deleting and then re-installing.
Like I said, the plugin seems to work fine, but this error/issue doesn’t seem very random to me.
There were a couple of users that reported the issue in the past but I have never been able to reproduce it. I don’t have enough data to pinpoint it.
Even a Google search doesn’t give anything useful (https://www.google.com/search?sourceid=chrome&ie=UTF-8&q=The+plugin+does+not+have+a+valid+header.).
@ulrich Sossou
I don’t disagree with you. I just find it odd.
No problem. I will make sure it is fixed as soon as I have any clue about its cause.
I just uploaded a new version of the plugin. Let me know if it fixes the issue.
I just tried to install the plugin and ran into the same issue “This plugin does not have a valid header”.
