I have just installed IP inside my wordpress site. Everything works fine other than Add Client and Add Payment page. Clicking those links takes me to the Wordpress 404 page. Can anyone help me what I missed?
Just noticed few more pages are also not working Custom_Field & User Profile page
Read the red box on top of this page… 
Hi,
After updating from v1.5.3 to v1.5.4
I’m having the exact same problem. So far also for the Add Client and Add Payment pages.
I checked the red box on top.
I get these error ERR_EMPTY_RESPONSE when I click on Add Client
Also I activated the debug, but i can’t see anything.

Already thanks for the good work, updates and support Kovah!
Couldn’t of checked very hard 
This is has been resolved countless times, please refer to: InvoicePlane 1.5.4 released
Also tried that!
Or the line is not correct anymore in the current version.
@nmay1990 do you know what the line of code currently is and needs to be changed with array_push($field->$field_id_fieldlabel, $custom_value->custom_values_value);
Hmmm strange. It worked when I tested it several weeks back. Unfortunately I can not look at the code right now.
If it’s possible and doesn’t cause issues with anything else running on your server you could try upgrading php to 7 / 7.1.
Hi,
Yes that what i’m now looking for how to upgrade to php 7.1 in directadmin. Hope than the problem is solved.
But if you have time tomorrow, to check in your code would be great. I think the excact line is not correct anymore.
The fix is still working with the latest version available from the InvoicePlane website.
If it’s not working wait for the upcoming release on next sunday.
Hi Kovah, nice!
So far i have got to upgrade to php 7.1 with succes.
Ps: also found this bugs maybe you it can be fixed in the release?

https://community2.invoiceplane.com/t/topic/5151/13?u=myedgy
and
https://community2.invoiceplane.com/t/topic/5151/7?u=myedgy is still not working, i’m now download the pdf and send it manually by mail via outlook.
All the bugs you mention here are fixed for the next release version
I don’t understand your problem about download the PDF and send it manually by mail ?
Well when I try to send a quote to the users email, i get this output error. They said it was fixed in 1.5.5 but it still not working. So I create the quote PDF instead, save the pdf and send it one by one by my mail client. As with InvoicePlane I always get this error below.
Kind regards.
