the problem with determining my location turned out to be simple. Only in one city the coordinates were not registered.
I managed to determine this error only on version php7.4, which immediately, when searching for a location, determined only the city in which there were no registered coordinates. On the php8.0 version of the city, it simply did not determine any and there were no errors. By adding the coordinates everything worked.

@Vlad7
Did you have "null" there?

Yes, out of a large list of cities, only one city had empty latitude and longitude lines

@Vlad7
Thanks, SQL just need a bit of coalesce, will be implemented in next update

Need to check what is on those lines. 

Good day!

For the modification of the Epsilon theme to ensure that the
location' on each published display product card at the home page,  premium box section and the search page has this format "city, region, country" just like the delta theme format.

Instead of the Epsilon theme default "city, country"

How much will it cost?

Thanks
