I have installed the OJS 126.96.36.199, and it was recently transferred to a new subdomain. After, I tried to download some documents inside the system, and I receive the following error:
[25-Sep-2020 12:39:26 UTC] PHP Deprecated: Non-static method PKPApplication::getRequest() should not be called statically in /home/colnesor/pub.colnes.org/plugins/themes/bootstrap3/BootstrapThreeThemePlugin.inc.php on line 129

I would appreciate any kind of advice on how to solve this. Regards,
