0 [] operator not supported for strings when selecting configuration option

[jankoo]

Some people have reported problems with PHP7.3 so it is advised to use no later than 7.2 currently.

ok.. now i have it also on php 7.2.13.. so what version should i use?
it wont be fixed for all?

[jenkinhill]

7.2 is fine.

7.2 is fine.

i dont have this option on hosting.. on none of the php versions i cant open the settings 
i can have 7.1.25, 7.2.13 or 7.3.0

what i can do? why important thing as this still dont work.. its issue from 2016?

7.2.13 ==  7.2

they are sub versions

If u want the  0 [] operator not supported for strings fixed u need to do the research to find WHERE this is being thrown .. most of my sites are on php 7.3 and I haven't seen this error since all ( most? ) were found months ago
could just as easily be in a 3rd party plugin etc etc

Meanwhile it should also run on php7.3, if there are good bug reports, we can provide a fix. But the current main php version is php 7.2
