Just realized I was getting this error
“contextual_help is deprecated since version 3.3.0”
Used the following fix posted by @paulgooch
Error is related to WP Mail Logging –
First deactivated then reactivated the plugin to verify the error was associated with this plugin.
Next went to the Plugins Editor within the WP Admin section and found the following file.
FWPML_OptionsManager.php uses the variable $contextual_help.
Used the Find feature in the plugin editor to locate each instance of the tag “contextual_help” and replaced them in the file with “wpmail_logging_contextual_help”
This resolved the issue and error is no longer showing up.
Thank you @paulgooch
