Once the theme and child theme is installed, the site works and displays the standards default theme style. The problem happens once I activate a demo template. Activation of any demo template causes the entire site to stop working. This means that all admin WP content returns a blank page and going to the site as a visitor also returns a blank page. All pages contain the following code after activating a demo template:
<!-- SHTML Wrapper - 500 Server Error -->
Nothing I do resolves the issue and the only way I can get the site back is to wipe the directory and do a fresh install. Via FTP disabling plugins does nothing; regardless, If I've only activated the 2 required plugins or all plugins, required and suggested.
Comments
please contact with your admin or hosting provider because 500 is an Internal Server Error and all details about this error, can be found on server back-end only.
