WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: how to fix php errors when previewing/installing themes., by mth1 Hi Rajan, Thanks so much for your help and for suggesting the nifty health check plugin. Everything appears to check out fine, but the php errors persist on all themes other than the twenty themes despite everything being deactivated and the use of a clean up plugin tool. Nonetheless, I at least know now that the php warnings relate to the ‘ASBPath’ so I’ll persevere with finding a solution. Much appreciated!
