The easiest solution i can think of would be to install:
https://wordpress.org/plugins/wp-migrate-db/
and do a search and replace on the database, replacing your old filepath with the new one (this will resolve any issues with this plugin and any other plugins in the future):
base on your log file im guessing its:
/data/sites/web/onderwijscommunitynl/www
to
/home/hrcommun/domains/onderwijscommunity.nl/public_html
Please make sure you backup your database and files before doing anything like this.
Thank you problem is fixed!
