Template Style Error

I also get the same error when I try to edit a SP Simple Portfolio: Items in pagebuilder and have no way of editing the page.

here is the error URL

https://www.accountantswebdesign.us/index.php?option=com_sppagebuilder&view=form&tmpl=componenet&layout=edit&extension=com_spsimpleportfolio&extension_view=item&id=28

any updates on why there are these errors?

2 days and no response.... ??????

Now I get
0
Failed to parse time string (273790702722-12-21T17:42:55+00:00) at position 11 (2): Double date specification

No response still????

Can someone look into why I get this 403 message and why the formatting is screwed up on the template options page?

When I installed the template, the shaper_helixultimate template was not installed as part of the package, even though PageBuilder is installed.
The problem was when I went into Templates: Styles (Site) > investa - Default > TEmplate Options the control menu on the left of the screen was not presenting properly.
When I installed the shaper_helixultimate template and worked through it to set up the site, the menu was fine and the 403 error disappeared.
There is something wrong with the template or maybe it is the process of installing the template and not including the shaper_helixultimate template that is at fault.
