    Hi,

    I have a strange problem: if I try to validate anything, like updating a page, while I’m using wordpress admin, I get a blank page. The URL is god but nothing loads, not even an error message.
    I’m working on local machine. Do you have any idea why I get this ? I tried to switch themes but it doesn’t work. Should I try to reinstall WP and all the plugins ?

    Thank you !

  • Hi,

    Something is wrong with your localhost setup. Problem with localhost is it doesn’t show errors on most setups (php mode is set to hide all errors).

    If you can grab your localhost apache php config file (php.ini), try to enable error_reporting on ALL. Something like that:

    php.ini
    ——-
    error_reporting = E_ALL

    That should help you debug trouble, but as it’s a localhost problem, the quickest way would be to put this setup on a cheap cloud to bypass many potential issues.

    thank you ! the thing is I’m learning, I’m a noob. And I have 10 or 20 php.ini files on my mac. I don’t know where I should look for this file…

    MM, not a mac pro either sorry, but it’s like Linux.

    Should be in a directory like that:

    /etc/apache/php/php.ini

    You can sort it by last read access to get the file in between the 20 too, while trying to load your page

    Thanks again for your help.
    the php.ini files are in /mamp/php/php5.4.42/conf/
    there are 6 versions of php, so 6 folders, each with a php.ini, but it seems in all of them there is “error_reporting = E_ALL”.

    I tried reinstalling wordpress, updating plugins but it doesn’t work…

    I went to check the php_error.log, I get many errors like these ones

    So I resolved the problem by deleting the plugins that are mentioned above. They were installed with the theme accesspresslite, and it seems the installation didn’t go properly. by deleting them I solved the problem, thank you for your help ??
