Hello, Nnamdi O.,
To fix the problem you need to fix the memory error first – https://prnt.sc/XD4vUHKzRUOA It is important, as you can see in the docs of Elementor we provided – https://prnt.sc/q3wT8oSqL4ij
It is because you are using a lot of plugins all of them need memory, so disable a number of 3rd party plugins or contact your hosting provider to solve the memory error.
We hope for your understanding.
Kind Regards,
