problems with entering and updating records

Submitted by J.M.Heap on
This is the message I get when submitting a record:
 

An error occurred when the data was submitted.
 

Saving the sample data was succesful, but 1 image failed to save.
The file o_1ju2hch2k136sdssu8b116c2a2c.jpg does not exist and cannot be uploaded to the Warehouse.

 
This is the message I get when trying to delete a record:
 

An error occurred when the data was submitted.
 

Attempt to update existing record failed - website_id 23 does not match website for sample id 37315711

 
The original record does in fact go through OK in spite of the message but in the mean time I may inadvertently create duplicates by re-entering a record on the assumption that it didn't work. Actually, the system seems to create a duplicate anyway which I then try and delete. 
 
Also, the website brings up the privacy settings display every time I click anywhere on the site, even though I've 'saved' my preference.
 
I don't know what's going on. Is it me or iRecord? I've not had these issues previously and I'm doing nothing different.
