“Validation failed – Value must not exceed -4 characters” ?!!

Hi,

May I ask how you resolved this issue? I am currently receiving the same error, but have no idea why it’s doing that and no idea how to fix it. It doesn’t seem to be any of my other plugins causing the issue.

Thanks!

Been digging all over the place, but I think it was something due to WP 5 upgrade that messed up the settings for the ACF fields, so go into those specific fields in ACF plugin and make sure there is no any funky validation set in them – you’ll probably run into that weird validation set in the field settings directly, so just remove it and save the field again.

I ran into this issue as well. I noticed the issue after upgrading to WP 5.1.1 and ACF Pro 5.7.13, from 4.x and and ACF 5.6.x.

The field was a text field inside a repeater field, but my error was -20 characters rather than -4.

Luckily the issue was fixable. I ended up exporting the field group via ACF’s export tool, editing the JSON file, deleting the field group in the CMS, then importing the fixed JSON via ACF’s import tool.

I’m not sure what actually caused the maxlength value to be -20, but I changed it to “”.

Here’s an excerpt of the JSON with the issue present; see the maxlength value:

                            {
                                "key": "field_56bcbf54511cf",
                                "label": "Name",
                                "name": "name",
                                "type": "text",
                                "instructions": "",
                                "required": 0,
                                "conditional_logic": 0,
                                "wrapper": {
                                    "width": 100,
                                    "class": "",
                                    "id": ""
                                },
                                "default_value": "",
                                "placeholder": "",
                                "prepend": "",
                                "append": "",
                                "maxlength": -20,
                                "readonly": 0,
                                "disabled": 0
                            },
