can you check with your host what PHP version and what the PHP memory limit is?
Version should be at least 7.x and memory a minimum of 128meg, would recommend at least 256meg.
It’s working on my colleagues computer – I will continue working in incognito for now and close all windows / restart browser and clear cache shortly and I think it should be fine.
Many thanks for your help – I’ll mark this as solved.
You’re welcome – sounds really silly but sometimes you actually need to complete restart chrome… which sometimes requires switching your pc off and on 🙂
