POST data can’t be buffered

    Hi Tobias,

    I had already mentioned my problem in the following post: https://wordpress.org/support/topic/error-saving-failed-ajax-call-failed-2/#post-11025624

    In the meantime I had contacted Dreamhost and they have adjusted the following values on the server (phprc):
    max_input_vars=10000
    upload_max_filesize=104M
    post_max_size=105M
    max_execution_time=500
    max_input_time=500
    memory_limit=256M

    Now I still have the problem that if I want to make a change on a page (for example our home-page) that contains a table, I get redirected to the “Posts” list in the WordPress user interface and my changes are not saved. Normally when I change something on a page, the user interface stays in the “Edit Page” mode.

    When checking the errorlog of our Website I see that I get “[Tue Jan 15 04:54:37 2019] [warn] [client 46.223.128.66] mod_fcgid: stderr: PHP Warning: Unknown: POST data can’t be buffered; all data discarded in Unknown on line 0, referer: https://www.coralia-liveaboard.com/wp-admin/post.php?post=5&action=edit”.

    This is exactly the time stamp when I tried to save my changes on the page that contains the table. However, I wonder how this happens because I’m not actually editing the table – I’m just editing a page that contains the table?

    It would be great if you could let me know. In the meantime I had adjusted the values in “phprc” further to:
    max_input_vars=50000
    upload_max_filesize=104M
    post_max_size=200M
    max_execution_time=1000
    max_input_time=1000
    memory_limit=256M

    But that didn’t help, I’m afraid.

    Thanks in advance and kind regards

    Hi,

    thanks for your post, and sorry for the trouble.

    Unfortunately, I have never seen such an error before, and to be honest, I don’t think that it is related to TablePress in any way. TablePress is not actively involved in saving posts or pages.
    So, I’m afraid that I’m not able to help with this server issue, sorry.

    Regards,
    Tobias

    Hi Tobias,

    thanks for the fast reply. I posted it now in the “Fixing WordPress” forum and I hope they can help.
    I suspect they will suggest to disable your plugin. But I would really like to continue using it.
    If I temporarily disable the plugin, will the tables still be there or do I need to export them?

    Thanks again & kind regards

    Hi,

    no worries, the tables will still be there after deactivating TablePress. Of course, it’s always good to have a backup, so I recommend to export all tables to the JSON and CSV formats (in a ZIP archive), and to maybe create a full database backup. That will be helpful for other problems on the site in the future as well.

    By the way, my guess is that the server has some security software installed that is checking something too aggressively and has a false positive here, e.g. when checking for possible security threats or attacks.

    Regards,
    Tobias
