Ubuntu 16.04 - Blank Page / Error, try with Firefox

Meant to put, that if I view the source of the page I can see text about Try using firefox - but it doesn't actually display anywhere.

Hi Ian,

Please try having a look at the php log files and see if any errors come up. It is possible that a module is missing such as php-xml

Adam

Hi Adam

No errors appear in the error.log file that I can see, I've checked and php-xml is installed and enabled. I'm not sure what else to check!

Thanks

Ian

Hi Ian,

Can you please provide some more detail about the server you have installed queXS on - i.e. the distribution, the version of PHP and Mysql used.

An up-to-date list of the queXF requirements can be viewed inside this Docker file:

https://github.com/adamzammit/quexf-docker/blob/master/Dockerfile

Adam

Hi Adam

The server is Ubuntu 16.04.3 LTS, running Apache2.4.18 and PHP 7.0.22-0ubuntu0.16.04.1, MySQL server 5.7.21-0ubuntu0.16.04.1

ADODB was installed using apt-get install libphp-adodb - don't think I need to do anything else more than that, source file reveals it's version 5.20.3 - Is ADODB supposed to be listed in phpinfo? If it is then perhaps I haven't enabled it properly but not entirely sure how else to do that (and my googling isn't turning up anything useful)

Been through the Docker file and installed the extra bits from your apt-get list but it just appeared to be the OCR stuff that was missing.

Thanks in advance.

Ian

Thanks Ian,

Can you please include the details of your config.inc.php file
(excluding any passwords of course)

Hi Adam

I'll test properly when I'm back in work next week, however a quick test and it seems to have kicked into life somehow.... Not sure what, if anything has changed, or just importing that file has restored/restarted something but at the moment it's looking promising!

Will update you next week.

Ian

Thanks Adam Zammit, that solved my question.

Hi Adam

Not sure what else has changed but it does appear to be working correctly now.

I think there is posisbly a level of confusion on my end with certain pages too, as if no form exists then it just loads as a blank page where as I was expecting some text/somethign to display not just a white page. Therefore potentially it has been working for longer then I have realised but I've not picked up on it.

Sorry for wasting your time, but thanks for your patience!

Ian
