When I try to install plugin my website i got the error
**
Installation failed: There has been a critical error on your website. Please check your site admin email inbox for instructions.Learn more about debugging in WordPress.

and also when i want to update my theme
error Unable to communicate back with site to check for fatal errors, so the PHP change was reverted. You will need to upload your PHP file change by some other means, such as by using SFTP.
Also, what plugin are you trying to install. The type of thing you’re referring to commonly happens on Wordpress for plugins more than 10MB. If it is, I suggest that you upload it bit by bit using Filezilla.
I installed Updraft literally yesterday so follow these steps carefully:
1. Click here
2. Click download and then extract the file
3. Go to htdocs > wp-content > plugins
4. Create a directory/folder named updraftplus and enter it
5. Open your downloaded file and move everything to your created directory
