I'm actually trying to setup a wordpress environment on App Engine standard. I'm facing a problem with a Wordpress plugin, Visual Composer : https://wordpress.org/plugins/visualcomposer/.
It looks like wp-content directory is read-only, as mentionned in Google's docs. Therefore visual composer is trying to write in, and I get this error 'mkdir(), Enable to write to wp-content - read-only directory'. Any others persons are experimenting this issue ? Is there a way to put wp-content in writable mode ?
Thanks
