at the bottom of the updater it says your current version is 1.13.2 - in this state i-doit is only able to update to the next major version (= 1.14). After this you should be able to update to 1.14.1 or directly 1.14.2
maybe this information is useful:
I had the same problem and always got the message "CSRF-Token mismatch" when trying to login. After some investigation I found out, that our server hard disc was totally full. Getting some free space made the login working without problems.
@kelv1n , @langelange it's confusing because all the logic is present on i-doit except the render of qr codes in gui, but it is a pro feature. However, you can switch to barcodes in Administration > System settings > Tenantsettings.
In i-doit 1.12.2 we introduced a new licensing logic - unfortunately we forgot two places where to strip the code for our OPEN release. This will be fixed with the upcoming Version 1.12.3 in about three weeks.
Just noticed that the import csv was only available on the pro version. I think it would be nice to add this mention to the KB: https://kb.i-doit.com/display/en/CSV+Data+Import as I suspected something like that and expected to find a mention is the article.
in the global search you can search for IP address or part of IP address as a text.
So searching for "192.168.2." will show all entries with IP addresses starting with it.
Of course, the search will also find entries with that text in other fields like description.
For specific lists, reports might be better for you.
