Answer 1

Generally, this error caused due to incomplete update process of plugin. This might server-side error. We can solve it via replacing plugin files from the WordPress repository.

1. Go to cPanel > File Manager or FTP 
2. Go WordPress installation folder > wp-content > plugins > ocean-extra
3. Locate and delete a folder named in step 2
4. Now, download the plugin manually from https://wordpress.org/plugins/ocean-extra/
5. Upload and extract the folder in the same plugins folder
6. Done.!

Answer 2

Replace The Old plugin Folder With New One
