Divi Visual Builder won't open

It sounds like you need to change the php settings in your hosting account. Change your php settings to the following variables:

• memory_limit = 128M
• post_max_size = 64M
• upload_max_filesize = 64M
• max_execution_time = 120
• max_input_time = 60
• max_input_vars = 1000
• display_errors = 0

Also make sure that both your divi theme and wordpress version are up to date.

You can find the php settings by first logging into your hosting, clicking on your Cpanel, and making your way to the MultiPHP INI Editor (Might have a different name with your particular hosting provider). Then select which domain you want to change the settings of, and it will show you all of the php settings. If push comes to shove and you just can't seem to find out how to change the php settings yourself, just reach out to your hosting provider and ask them to change them for you.

Hope this helps!
