Hi @ILYASS_SABER,

Are you able to access your PHP error logs and report on errors found there? Those error messages usually provide more clues as to what the issue occurring is.

Did you configure the allowed_hosts variable in config.inc.php ? See e.g. Server host www.domain.com not allowed!

Hi @ILYASS_SABER,

I’m not sure… did you try what was suggested around configuring the allowed_hosts? If so, what was the result?

Hi @ILYASS_SABER,

If you’re able to reproduce this error with a specific request, look at the page output and see what is displayed. Do you have any modifications or plugins that generate output where it shouldn’t be? Is it possible that you’ve introduced whitespace accidentally to the start of a .php script?

No, I did not add any php code

Also pdf doesn’t work

@asmecher @mpbraendle @rcgillis
can you help me please

Hi @ILYASS_SABER,

You’ve got spaces appearing before the PDF code starts in the PDF file, which causes the file to seem corrupted. Along with the error message above, I think this means that something has added whitespace to the top of a .php script.

Here’s a StackOverflow thread about the problem and some ideas for how to resolve it:
https://stackoverflow.com/questions/12415675/find-whitespace-injecting-php-files

OJS source code does not come with these, so someone or something must’ve added them on your server. You’ll have to find and remove those spaces.
