503 Service Unavailable when saving

    I am currently testing the free version. My survey requires about 60 sections with one question per section. The question includes an image (100kB), a caption, and 8 answer options of the radio type.

    This causes issues when I approach 30 sections.

    At that point, it is no longer possible to save. When I click on save, the page loads for a long time and then I get a 503 Service Unavailable error.

    I have no other plugins installed, I am using the latest version of WP and Survey Maker and PHP version 8.1.31 with these settings:

    max_input_vars 10000
    max_execution_time 600
    max_input_time 600
    post_max_size 256M

    This is the error log:

    Any suggestions?

    Dear @mrshoreline,

    Thank you for your patience.

    After thoroughly checking, we have determined that the issue is likely related to server limitations, as we observed the following line in the error log:
    ModSecurity: Request body no files data length is larger than the configured limit (131072).

    From this, it seems that you are trying to save a large amount of data, and your server’s current limit is preventing the save from being completed, which is causing the issue.

    We believe the solution might involve either contacting your hosting provider or increasing the limitation directly in the ModSecurity configuration on your own.

    Unfortunately, there’s nothing we can adjust from our plugin’s side, as server configurations cannot be modified at the plugin level.

    We have also found the following link, which you may find helpful to review:
