WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. Features include a plugin architecture...
WordPress cannot update plugins because it cannot write files. What should I check?
Check the full message and the directory it mentions: the cause may be file permissions, ownership or a storage limit. If application logs are available, look for the error recorded when the update failed. Do not share passwords or sensitive paths when asking for help.
Before changing permissions, keep a copy of your files and database. Do not apply 777 permissions across the site or change file ownership recursively without understanding the server configuration. Ask your provider to check which user runs PHP and which permissions are required. Once corrected, try updating a single plugin and check the site.
