According to my ISP (GoDaddy), I am currently on PHP 5.6, and it's offering me PHP 7.0, 7.1 and 7.2 as upgrade options. Since I don't know anything about PHP, I need to know, is there any reason I should **not** upgrade to the latest version? --------------------------------------------------------------------------------------------------- ### What version of WordPress were you using? 4.9.8 --------------------------------------------------------------------------------------------------- ### What Theme and what theme version were you using? Deja Vu 2.8.6 (is this the latest, or have I fallen behind?) ---------------------------------------------------------------------------------------------------
