Hello,I have just installed koha 3.18. I got an error message as shown in the image below I realized I couldneither create patrons nor set library.I thought it was because of the version, so, I reverted to3.14. I can now set librarybut can not delete some of the alreadyset libraries that came with the installation because they have patrons. Each time I tried creating / viewing these patrons, it takesme to this page What am I suppose to do please.Thank you. Akpokodje Vera N.
