in a nutshell: it’s not about excluding other/non-selected things, it’s about the chosen item (or category) to be available at the the times/days/dates set

obviously , this is time and timezone dependent (and i do not know what TZ you are in)

However, bearing that in mind , at the moment i can’t see the problem ….

your settings say that item (Orange Ginger Chicken Wings …) should be available on 20/07 to 27/06 between 0:00 and 23:45, Tue to Sat

it’s Tue, it’s between 0:00 and 23:45 and its the 20th/ June , so it should be available (as it is)…?!?

why do people always want to edit files, write code and whatnot when they can just click on

[ORDER PAGE] : allow editing/amending of ingredients on the order page

in the options page of the plugin ?

lol

(unless i completely misunderstand)

do not CHANGE core files/things, ADD things , overwriting styles

did you read this ?

PPS:
the wppizza plugin just sends emails programatically. what the mailserver does with it i have no control over.

sure if you/they see something in the *mail* server logs (or any other logs) that gives us some evidence that the wppizza plugin is at fault, i am happy to investigate. anything else is just a “go away, i cannot be bothered” let’s make up some other excuse that it is someone elses fault our server falls over (which may of course be the case, but they need to provide some evidence to that effect)

ok,

there’s one thing that just sprang to mind – this might or might not at all be your issue, but it *could* explain why things randomly fall over

the default memory for WP is 40M which is fine if it’s just a simple blog.
if you have a lot of plugins running and complicated theme’s stuff ect etc , this will be eaten up quickly and your site will fall over (though i would have thought this would show up in the debug logs if it’s the case…)

I would suggest you increase the limit to something more useful like 128M
so, in your wp-config.php add
define('WP_MEMORY_LIMIT', '128M');
before the happy blogging line

again, just a guess, but there is no harm done doing this

that said, a “high load on server” as your hoster mentioned is something they need to look at .
the above is unlikely to make much of a difference if the server is under attack / has no firewall or a million other things that could be the cause for a high load

>Life…
Lol

sorry, but i am really not sure what you want me to do about this.

>quote: Then suddenly I wanted to access wp-login at around 18:00 and it’s not loading up – the wordpress is not accessible, 502 bad gateway and internal server error. 5 minutes later website is up , next 5 minutes website is down.

this is clearly server’s end , especially given your screenshot here
https://ibb.co/ekhsQ5 (i.e server load is high). if the server falls over it wont receive any feedback from worldpay (as it’s not accessible) . there’s nothing i can do about the availability of your server

furthermore, though this might cause mis-interpretation because it happens to use the same terminology , “502 bad gateway” has nothing at all to do with the worldpay gateway (502 is a *server* status code – see https://www.google.co.uk/?gws_rd=ssl#q=502+bad+gateway)

as mentioned previously , the php *notices* in your debug log are inconsequential

looking at your admin, wp total cache is also seemingly not setup correctly or setup was not finished. together with session setup issues / memcache not setup as it needs to be in conjunction with sessions etc this might well cause all sorts of issues.

Only your server people will be able to tell you where the high load comes from

>. At times we had a situation here and there where we couldn’t access the site itself or wp-admin,

which is the bit you/your host needs to fix.
when it happens you need to find out what does it . if the site is not accessible then – obviously – there is an issue.

now you have enabled debug, you still have this error (except it’s now in the debug log itself)
is_writable() [<a href='function.is-writable'>function.is-writable</a>]: Unable to find the wrapper &quot;tcp&quot; - did you forget to enable it when you configured PHP?

you need to speak to your host about this (see above link somewhere) the problem here is not the is_writable but that your session save path is set to tcp://..... (that’s my best guess admittedly. maybe for memcache it needs to throw these errors. i dont know)

the “PHP Notice: Undefined variable” etc are inconsequential

Hi,
a couple of things

a)
>We have contacted the TSO Hosting site and they said it is plugin problem not the server
>But when we tried to login at the times of trouble we had “Internal Server Error”:

an internal server error is exactly that . i.e clearly a server error. (although it might be cause by a lot of things)
i suggest you turn on debug and see what the exact error is (see https://support.wp-pizza.com/topic/how-to-enable-debug-in-wordpress/)

b) the worldpay plugin/gayeway has not changed for over a year so when it suddenly stopped working after 20:00 what (did you / someone) change(d) at 20:00 ? i certainly did not change things…
you should check your mail server settings (though if the order does not even show up in the order history it suggests the email did not (programatically) get send – see debug above as -again – this can be cuased by many many things before the site even gets to try to send emails

c) your setup also throws a bunch of errors
(see /wp-admin/edit.php?post_type=wppizza&page=wppizza-tools&tab=sysinfo)
and a VERY – lets say unusual – session save path (not even sure if this path would work at all.

I am no expert on memcache but am reasonably certain other people use the plugin with memcache without issues

when i say “it will never do that.” i am referring of course to natively implementing it.
i am naturally not preventing anyone from doing such a thing
