Hello @pastorcg
The error you get is from WP, not being able to write to your wp-content/plugins folder
I would fix that problem first then try again upgrading. Here is an helping page: https://developer.projectdmc.org/advanced-administration/server/file-permissions/
Hello @litetim
You are absolutely right. We had reached a maximum number of file handles on our “unlimited” account with our hosting provider. There are several hosting attributes that are technically unlimited (storage, email accounts, databases, etc.), but the number of files has a hard maximum and we reached it. After cleaning up some older content across our domains, I was able to successfully update the plugin.
Thanks for your help!
