Deprecated: version_compare(): Passing null to parameter #2 ($version2) of type string is deprecated

[gianlucagiacometti]

Please prefix your issue title with one of the following: [BUG], [ISSUE], [FEATURE REQUEST], [MODULE REQUEST], [OTHER]. (I suggest to add something for these cases, like DEPRECATED or PHP-ALERT, since it's neither a bug nor a real issue)

Replace everything between stars with current version of your facileManager and module installations:
fM Version : 4.5.0 fmDNS Version : 5.3.4

In raising this issue, I confirm the following (please check boxes, eg [X]):

• [X] I have read and understood the contributors guide.
• [X] I have checked that the bug-fix I am reporting can be replicated, or that the feature I am suggesting isn't already present.
• [X] I have checked that the issue I'm posting isn't already reported.
• [X] I have checked that the issue I'm posting isn't already solved and no duplicates exist in closed issues and opened issues
• [X] I have checked the pull requests tab for existing solutions/implementations to my issue/suggestion.

I confirm, I also saw similar messages on the same software versions

This message hangs and is not removed, if you close the browser tab and restart, you can see that the config building is successful

This is now fixed in fmDNS 6.0.0 and later.
