Hi 
Yesterday I can access the website properly, but when I tried accessing it today it doesn’t load properly. What might be the cause of this? Thank you so much.
Can someone help me please? 
I tried installing omp again, but its still the same. I’ve been using OMP for 3 weeks now, but since saturday this is what happened.
Hi @shamae_507,
Have you checked your PHP error log to see if there’s something relevant?

Hi @asmecher, I tried re-installing OMP a couple of times, the header, footer and everything else already appeared properly but the contents just loads.

@asmecher Hi! Sorry but I don’t know where can I locate it. I’m new at this and I don’t have enough knowledge in PHP. Where can I see the PHP error log? Thank you.
Hi @shamae_507,
That’ll depend on your server’s configuration; if your host has a knowledge base, it’ll be somewhere in there. See e.g. this Stackoverflow thread.

Hi @asmecher, I found an error log. Is this the one that you’re talking about? Thank you.

Hi @shamae_507,
Yes, that looks like the PHP error log. Some of those warnings suggest that the format for your allowed_html setting in config.inc.php is in the wrong syntax – check out the example in config.TEMPLATE.inc.php. I suspect your server is configured to send PHP error messages to the web browser, which can cause problems in subrequests that then have PHP error messages jammed into them. I would suggest checking your display_errors setting (both php.ini and config.inc.php) to ensure that error messages are logged, rather than sent to the browser.

Hi @asmecher, I checked out config.inc.php and config.TEMPLATE.inc.php. I think they have the same syntax. I’m sorry if I have lots of questions.

Hi @shamae_507,
What version of OMP are you using?
Regards,
Alec Smecher
Public Knowledge Project Team
Hi @asmecher, sorry for the late response. I already tried installing different versions but all the outputs are the same.
Hi @shamae_507,
Start with the latest release (currently OMP 1.2.0), and post a current PHP error log for that version, and I’ll see if I can help debug.

Hi @asmecher. I tried the installing the latest version and it here is the output. 
I checked the PHP error log and it says
[08-Feb-2017 17:49:37] PHP Parse error: syntax error, unexpected ‘{’ in /home1/pnuresea/public_html/po/omp/lib/pkp/lib/vendor/ircmaxell/password-compat/lib/password.php on line 10
Hi @shamae_507,
What version of PHP are you using?
Regards,
Alec Smecher
Public Knowledge Project Team
Hi @shamae_507,
Are you sure? I’m using PHP 5.6.29 myself without problems. The error message suggests you’re using something older than PHP 5.3.7, which is required by the password_compat library we use.

Alec Smecher

Hi @asmecher, yes. I’am sure. It works now. Here is the output…
I checked the PHP error log,and it still says
“[08-Feb-2017 17:49:37] PHP Parse error: syntax error, unexpected ‘{’ in /home1/pnuresea/public_html/po/omp1.2/lib/pkp/lib/vendor/ircmaxell/password-compat/lib/password.php on line 10”
Hi @shamae_507,
Can you post a link to a phpinfo script? Also check to make sure that the file permissions on your cache/ subdirectory are permitting OJS to create/manage files there.

Hi @asmecher, Sorry but I don’t know how to post a link to a phpinfo script and how will I know if its permitting omp to create and manage files there? I’m really sorry. I don’t have any ideas.
