[Mapbender-users] Mapbender3-3.0.5.3: Error after updating PHP5 to PHP7

Wed May 3 00:14:32 PDT 2017

Hello group!

Last week we had to update our server including a switch from PHP5 to PHP7.
Everything worked fine, but after the update the digitizer element in
mabender produces an sql-error.
If the digititzer is activated, every move of the map produces the
following error-message:

*Feature API: Abfrage fehlgeschlagen."<!DOCTYPE html>\n<html>\n <head>\n
<meta charset=\"UTF-8\" />\n <title>An Error Occurred: Internal Server
Error</title>\n </head>\n <body>\n <h1>Oops! An Error Occurred</h1>\n
<h2>The server returned a \"500 Internal Server Error\".</h2>\n\n <div>\n
Something is broken. Please let us know what you were doing when this error
occurred.\n We will fix it as soon as possible. Sorry for any inconvenience
caused.\n </div>\n </body>\n</html>\n"*

The mapbender log shows the following:

The same is found in the database log (postgresql 9.6.2, postgis 2.3.1:

Some weeks before updating the server i ran a database update, but after
that, it worked as expected. So i dont think, the database-upgrade is the
reason for this.
Executing the sql shows the error, which disappears when the empty
where-clause is deleted.
I have just no clue how to handle this, so every hint would be helpful.

Thanks in advance
