I did some debugging around line 1542 in the flexible-content.php file

$title = '<span class="acf-fc-layout-order">' . ($i+1) . '</span> ' . $title;

when I var_dump $i, sometimes that value would be the string “acfcloneindex”. I didn’t get too deep into the weeds but it seems like ACF outputs a bunch of hidden fields (assuming for fast loading when the “+” button is hit) and those fields do not have numeric indexes.. I changed that line to:

$title = (is_numeric($i)) ? '<span class="acf-fc-layout-order">' . ($i+1) . '</span> ' . $title : '<span class="acf-fc-layout-order">1</span> ' . $title;

and everything seems to work. Not sure if this is a bug or not.

Looks like a bug to me, can you open a new support ticket for this here https://support.advancedcustomfields.com/new-ticket/ so that the developer gets the bug report.

Thanks. This bug is resolved since ACF 5.5.8

Hi

If I understand correctly this is fixed in the pro version, but not for the standalone repeater add-on?

We are seeing this issue in a project on which I can’t upgrade to pro, and I do still rely on the add-on, as there are no updates for the add-ons anymore I don’t think it will be fixed in there, but would it be possible to guide me in the right direction to solve this issue in my local copy of the plugin?

Thanks
Joren

Update:

For now I changed the line where the warning happens to the following:

<td class="order"><?php if(is_numeric($i)) : echo $i+1; endif; ?></td>

That seems to do the trick, at least for now. But I’m open for better solutions or an update of the add-on plugin 😉

You’re best bet would be to submit a bug report to the link I posted before. The addons are being updated. There is a new version of ACF that will be released to WP and the addons will still be available.

Not sure why you cannot update to pro, the new version (5) when released to the WP repo will likely cause the same issues. Maybe you should start a new topic on any issues you’re having making the move to Pro on this site.

Hi John

Ok, I must have misunderstood, I thought the add-ons didn’t receive any updates anymore.

Regarding upgrading, it’s not related to ACF or WP but more in the way we are hooked into everything with js etc to make sure a certain flow is followed while creating a post. There wille be a day that we have to do this but our planning for the next releases are to tight to make that happen.
