Losing plugin on update (3.0.5->3.06)

Go to your plugins page and see if MailPoet is still there but deactivated instead.

Just checked. MailPoet isn’t in the list at all.
(Of course I checked the activation, but I understand your point of view).
See a few other threads, same problem.

(It should appear here)

For me the complete plugin seems to be disappeared. I can’t reactivate what’s not there.

When I reinstall the plugin will I keep my members??

Just tried to add/reinstall plugin. On Add plugin page I can “reactivate” the MailPoetplugin.
When I try this then a message “De plugin heeft geen geldige “header””
(This plugin has no valid header).
(WP 4.8.2-nl)

Do you happen to know which PHP version your website is running on?

WordPress 4.8.2 gebruikt thema: Nisarg Child.
Running PHP version: 5.6.17-1~dotdeb+7.1
(Display PHP Version By David Gwyer)

Hmm, that’s strange. What if you completely delete it and download it again?

Trying to install with existing configuration.

Downloaded mailpoet.3.0.6.zip

In my WordPress dashboard, navigated to Plugins > Add New
Clicked on “Upload Plugin”
Uploaded the mailpoet.3.0.6.zip file

Bezig met installeren van plugin vanuit bestand: mailpoet.3.0.6.zip

Then:
Renamed /public/sites/www.je-photo.nl/wp-content/plugins/mailpoet/ to …/mailpoetOLD (FTP)

In my WordPress dashboard, navigated to Plugins > Add New
Clicked on “Upload Plugin”

At 17:31 (local time)
Uitpakken van pakket… (Expand)
De plugin installeren… (Install plugin)
At 17:45 still installing
At 19:00 still installing
Reload page
Are you sure you want to do this? Try again. I did go back.
Mailpoet is now possible to activate at the pluginpage.
Plugin active and most important, my subscribers are still there!

Thanks for your assistance!

It all seems OK now.
