Error message “Could not instantiate mail function”

FYI, I am also checking on the following document provided by your website(1), but it is a bit overly complicated to me so far, I am still trying.

For example, the document says “By choosing the Class File ’email_reminder.php'”, but the document did not specify where the php file is located, that is to say, I need to configure the php file by myself, and perhaps I don’t need to, like I said, the document is a bit complicated to me.

Hello,
The error message “Could not instantiate mail function” is raised by the WordPress framework itself, more precisely, by the PHPMailer class whenever our plugin tries to send an email message. All the email messages dispatched by our plugin are handled by WordPress, as plugins should not use their own email sending functions. The email messages can usually be sent by using two different transport methods: PHP Mail or an SMTP server. By default, WordPress uses the PHP Mail method, unless you install a specific plugin that allows to override the “mail transport agent”. Our free plugin Vik Mail SMTP is one of those plugins, and you should set it up in the same exact way you would configure a mail client on your computer or smartphone for what concerns the SMTP account details.

We invite you to reach out to our technical support through our website, as these issues are not directly related to VikBooking, because all the email sending functions are handled by WordPress.
Thank you.

Hi there,

Through the aids of my web hosting help desk staff, I kind of solve the issue now after installing a plugin WP Mail SMTP, just so you know.

Hi there,

Sorry, I just set this thread Unsolved again.

Although I had solved the issue by using a Plugin “WP Mail SMTP” along with the authentication of Gmail API, but there seems to be a potential limit of mails can be sent because of Gmail limit, so I am still trying to find a better solution to avoid the future sent-email amount limit.

Further more, since I am using my own work Gmail for the time being and temporarily get the email notification issue fixed, but the next step is that I need to let my client log in the website and see everything I did for her so she can evaluate about Vikbooking system. For that, I need to change the main email address, so, as far as I know, this main email address that Vikbooking used is the WordPress “Administration Email Address”, am I right? My web host help desk staff suggested me to create a Cpanel hosted email and use that email could save me from the complicated process of Gmail authentication demanded by the plugin “WP Mail SMTP”, so my guess now is that I need to create an Cpanel hosted email and fill it into WordPress “Administration Email Address” so that I can test if Vikbooking email notification’s function, pleas let me know if I miss something. Thanks.

KC

Hi there,

This reply is to update you the new development. I think I just found the option(1) where to set Vikbooking Admin email after my last post, so, I am considering to change Vikbooking Admin email/sender’s email by create a Cpanel hosted email to test the email notification function, or I might just change into another Gmail created for for client of this project.
