Hello!

For this error you can check our guide from here at point 5: https://forum.tagdiv.com/tagdiv-composer-not-working/
Also, try to deactivate ALL plugins except tagDiv ones, also if you are using child theme or cache plugin, deactivate them, clear all cache and try again.
Please also check the page for special characters and remove them if they exists.

Thank you!
