Not compactible or issue with coding

Hello,

First of all, I want to thank you for this quality product!!!

Writing this as feedback/issue with the plugin to be sorted on the reinstallation of the plugin.

After migrating(manual~ files and DB upload+ few DB config changes on WP-config.php file) from old to new hosting, the plugin throws an error with permissions to access certain files/folders, but all files and folders were given default 755 & 644 permission on cPanel filemanager, so reinstalled this plugin and now new error pops, as follows:
[15-Aug-2022 02:14:34 UTC] PHP Fatal error: Array and string offset access syntax with curly braces is no longer supported in /home(X)/(cPanel_Username)/(Domain_Pointed_Folder_Location…)…/wp-content/ip-geo-api/ip2location/IP2Location.php on line 382

***'()’ -> means values are different inside the brackets. hiding for hacker issues.
Error on-site shows critical error on the WP dashboard.

Thanks for all the help given here.
