Http error after update

Add-ons Bindings
1

After upgrade to latest OH on Openhabian-config the http binding does not update values and give this error:
[ERROR] [ab.binding.http.internal.HttpBinding] - given config key ‘format’ does not follow the expected pattern ‘.<url|updateInterval>’

Another reboot and it started to read values but still the error…

Check your http.cfg:

thx, but this is it:
x300.url=http://10.0.10.15/state.xml
x300.updateInterval=1000

If you’re using OH2 there may be a shadowcache of the config hiding that needs to be killed off.

what does “shadowcache of the config hiding that needs to be killed off.” mean?
How do you do this?
Cheers

Delete the corresponding xxxxxx.config from your xxxxxx.cfg in /userdata/config/org/openhab, then restart openHAB.
