Why is there a problem with hosting GTM code on the MODx site?

Question

MODX

Folks, getting back to the MODx topic.
I must say right away that I have never worked with her, I began to understand less than a month ago with a ready-made and working site. So the problem...
When placing the Google Tag Manager code in the page template, the page stops loading, or rather, the following is displayed instead:

{'MetaX' | snippet : ['tpl'=>'metax-html5']} {'topbar' | chunk} {'header' | chunk} {$_modx->getChunk('ContentType.' ~ $_modx->resource.template)} {'footer' | chunk} {2 | resource : 'settingsPrebody'}

Here is the template code (head without body):

Here is Metax html5 chunk code : https://codepen.io/alexej-trikoz/pen/ZmRgXj And MetaX snippet code (if needed): https://codepen.io/alexej-trikoz/pen/dQKxeo I tried to get around by installing the GoogleTagManagerMODX plugin. Installed and configured. I add a plugin snippet to the template - the same error crashes! Can you help with advice?

Answer 1

Just add GTM code to the chunk and don't use any MetaX.
