Welcome Back WP. It's been quite a while.
Would kindly suggest to make transition to a new layout slow & steady. Stability should really be your no. 1 priority. It is extremely annoying to put up with the BS of spam attack every now & then. Hopefully, your new host can live up to their claim Insha' Allah.
Its a lot different from what the site used to be like in the past. Perhaps you could introduce a bit darker interface (as an option). Too much white is not very pleasant for my eyes (it stings)
Glad to have you back with us. Cheers.
