To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. hmm, are you able to get the compiled SPIP view file? it must be a PHP script which can be used to reproduce this problem? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
