I just returned from a 10-day meditation retreat to find my website somewhat broken. I followed the protocol to deactivate plugins to isolate the offender and for me, it was the lightweight grid columns.
I am just wondering if there is a known issue with this GP plugin?
how odd – no other reports and i have a few site still running LGC that are working ok. Personally though i would recommend moving to Gutenberg Blocks for columns, which it looks like you have already done.
