XMS Web is beta version, it could have bugs.
Your funds are safe but some elements of app can return errors or even stuck.
There are few method to fix issues:
If you didn't finalize wallet yet but you receive errors:
Stop xmsweb.py.
Run xmsweb.py again.
Refresh browser page.
If your wallet is finalized but you don't see in/out transactions which should be there:
Click Stop process.
Click Run client.
Copy text, open new console and paste commands there.
Type rescan_bc and wait when wallet is synced.
If you made withdrawal but in tx list you see wrong amount:
It's normal, nothing to worry about. Sometimes it happens, to see correct amount need to import exported multisig info of other participant.
If you didn't open wallet for long time it needs time to sync. It can look like stuck.
Open terminal: cd xms && python refresh.py
Type number of wallet you want to refresh or type A for all wallets
