Fatal error memory exhausted in libraries/gantry5/vendor/leafo/scssphp/src/Parser.php - after clearing cache

I was trying to remove the label from the Favorites field (all I wanted was the icon).
- set the "Display Lable" to "No"
- had no effect
Then thought I needed to clear my cache
- cleared browser cache - no effect
- cleared joomla cache: System >> Clear cache
Now on that one category listing I get:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 130968 bytes) in /home/websmarticlescom/public_html/17025/libraries/gantry5/vendor/leafo/scssphp/src/Parser.php on line 1036

Now what should I look for?

Thanks for your time.

you have a memeory problem in your server ....
your code relate too gantry no flexicontent but i think you need more memory

Thank you for the tip/clue.
I'll look to another template (less bloated) than gantry based.
If you know of any light weight and responsive templates that work great with FlexiConent, please let me know.

Thanks again!

you can use ja simply, warp ... etc all template work with FLEXIcontent
