How to solve problems with the Avada theme?

Question

themeforest

Good afternoon, I bought the Avada theme. I downloaded it, imported it, tried to upload demo content, an error occurred with System Status. Raised all the parameters so that there would be no red values, enabled the xmlreader extension, because. was off. It seems that everything worked. Today I tried to import other content - the same error occurred. In the logs there is such an entry
