Sorry, I’m still not quite fully understanding what you’re ultimately trying to accomplish.
So, is the template you’re referring to the /JB9/templates/tpl-page-members.php file?
but when I do that and rename it.
For what purpose are you renaming the template? Templates copied to the child theme shouldn’t be renamed. The themes looks for specific template names associated with the theme.
Will the page display if the file isn’t renamed?
but the jobboard theme has css issues when I try to use toolset’s suite to create the extra functionality I want to add.
Is this a separate problem you’re experiencing than getting the template to display?
