 * Hello,
   Thanks for this really useful plugin.I have just found it and it seems
   to be the best for my needs about this EU legal requirement.It works all fine
   in most cases, but for one product it just stopped working and gave the below
   error message.The error does not happen at another products and only apperars
   if the `_eggl_show_garan` option is active. I am using the `[eu_garan]` shortcode
   as I have custom product page layout.
 * `PHP Fatal error: substr(): Cannot use output buffering in output buffering display

 * The `[eu_guarantee_notice]` shortcode works fine on all product pages, even on
   that one, where the `[eu_garan]` gives the fatal error when activated.
 * Please help me find out how this error can be fixed as I would really like to
   use your nice plugin.

 * Hi [@ucsendre](https://wordpress.org/support/users/ucsendre/)
 * Thank you for your kind words and for the detailed report. The environment details
   and stack trace were very helpful.
 * What we found so far
 * The error in the log (“Cannot use output buffering in output buffering display
   handlers”) is not the original error. Since version 6.9, WordPress processes 
   the whole finished page at the end of each request. If another error happens 
   during that step, PHP can’t display it and shows this message instead, so the
   underlying cause is hidden.
 * Our main suspect is that the page is using more memory than the 256 MB limit.
   The full GARAN label is a fairly detailed graphic. On variable products the plugin
   currently includes a copy of it for every variation, so a product with many variations
   can make the page very large. That would explain why only this one product is
   affected, only when GARAN is enabled, while [eu_guarantee_notice] works fine 
   on the same page.
 * Could you help us confirm this?
    1. Is this a variable product? If so, roughly how many variations does it have?
    2. Could you temporarily raise the memory limit in wp-config.php and check whether
       the error goes away?
       define( ‘WP_MEMORY_LIMIT’, ‘512M’ );(If your host enforces
       a lower PHP memory_limit, this may need to be raised in the hosting panel as
       well.)
    3. If possible, open the product page’s source (Ctrl+U) and tell us roughly how
       many times “eggl-widget–garan” appears.

 * Hi [@garanlabs](https://wordpress.org/support/users/garanlabs/) 
   Yes, this is
   a variable product with 35 variations.
 * It seems like I have found a solution and now all products work fine.
 * On your plugin’s settings page (/wp-admin/admin.php?page=eggl-guarantee-settings)
   the `"eggl_garan_position"` option was set to `"under_image"` and the GARAN banner
   image was added to the product gallery. I have changed this option to `"after_add_to_cart"`(
   which in my case did not change the position as I use the [eu_garan] shortcode
   in my custom product page layout) and now the GARAN image is not added to the
   product gallery and the error is gone.
 * With the `"after_add_to_cart"` setting I have two `"eggl-widget"` divs: one `"
   eggl-widget--garan"` and one `"eggl-widget--notice"`.
 * If I set the `"eggl_garan_position"` to `"under_image"` the page of the product
   with 35 variations does not load at all, but another variable product with 25
   variations works and it has 56 `"eggl-widget"` divs: 55 times `"eggl-widget--
   garan"` and one `"eggl-widget--notice"`.
 * I set this issue to resolved. Thanks for your response and again for the great
   plugin.
 * Best regards,
   Endre
