Very slow db request, then error

  • Pdf creation slowed down terribly suddenly 28s to process form submission. very long query linked to Wordfence plugin inserting data…
    Conflict possible?
    Now submit goes into an error web page:

    Error message detected - PDF file generation aborted.

    So if you disable Wordfence is the PDF generation slowed?

    If i disable the paypal feed, it works, when enabled, i get the error mentioned.
    And yes, disabling Wordfence make my payment page appear, no error.

    From everything you’ve told me it sounds like the problem isn’t with the PDF software. It may be some sort of conflict between Wordfence and Gravity Forms but there’s really not enough detail to make any definitive conclusions. You should continue going through Wordfence and Gravity Form support to help you pin point and resolve the issue.

    Testing more today with wordfence disabled. It seems the problem appears sometimes, independently from wordfence.
    Could it be linked to server load ? something else ?

    Do you have WP_DEBUG set to true in your wp-config.php file? That could cause slower generation times and lead to an error because it enables full logging in mPDF.

    Also, what other errors are in your PHP error log around this issue?

    Absolutely, i have WP_DEBUG set to true, but if it could slower generation time, i have been using it since the begining without any problem, it just starts being slow now very recently, and took from a few seconds to several tens of seconds. big gap.
    By the way, where are mPDF logs ? can’t see anything in standard wp debug.log file.
    Nothing wrong in this file, nor in standard Apache error.log or access.log files.
    Can you please mention where i should find mPDF logs ?
    Thank you very much

    mPDf doesn’t log to a file. It sends any errors to your PHP error log.

    Since Gravity PDF hasn’t had any major updates for 11 months, and the last patch was applied over 3 months ago, the problem seems like it is from another source. Without any further information that suggests Gravity PDF is the cause we won’t be investigating further.
