unable to add more than 186 rows with repeater field plugin…when I add more rows and click on update button, page doesn’t reload and shows just blank page..all other posts/pages update normally..
See this https://www.advancedcustomfields.com/resources/limit-number-fields/
Also, ACF can time out when there is too much data to be saved. This depends not only on the number of fields but what’s in those fields and how many queries need to be accomplished to do the saving. There is no fix for this. I suspect this may be part of the problem if you’re getting a blank page.
