Learned something new today… Also see the wiki:

Een kilobyte, afgekort kB, is 1000 bytes. Vroeger werd er verschil gemaakt tussen een hoofd- en een kleine letter k:

k = kilo (103)	1.000
K = kilo (210)	1.024

In praktijk werkte dit verwarrend en bedoelde men met 1 kB vaak 1024 bytes.

De oude notatie wordt ontraden sinds er een nieuwe standaard is voor binaire voorvoegsels (zie: veelvouden van bytes). Deze standaard wordt echter nog niet veel toegepast.

Let op: het is nog steeds van belang voor de B een hoofdletter te gebruiken: een kleine letter b staat namelijk voor bit en niet voor byte.

1024 B heet nu een kibibyte, afgekort KiB. 1000 kB heet een megabyte, 1024 KiB heet een mebibyte.

In een tabel:

symbool	naam	waarde	symbool	naam	waarde
kB	kilobyte	10001 = 103	KiB	kibibyte	10241 =210	2,4%
MB	megabyte	10002 = 106	MiB	mebibyte	10242 =220	4,9%
GB	gigabyte	10003 = 109	GiB	gibibyte	10243 =230	7,4%
TB	terabyte	10004 = 1012	TiB	tebibyte	10244 =240	10,0%
PB	petabyte	10005 = 1015	PiB	pebibyte	10245 =250	12,6%
EB	exabyte	10006 = 1018	EiB	exbibyte	10246 =260	15,3%
ZB	zettabyte	10007 = 1021	ZiB	zebibyte	10247 =270	18,1%
YB	yottabyte	10008 = 1024	YiB	yobibyte	10248 =280	20,9%

I ran into this issue: Any link in my code/theme/plugin to standard Woocommerce pages did not go to the correct translated page!
However the solution provided here will break whenever WooCommerce is updated. The correct way of solving this is adding some filters…

//20210216 - (c) My Brain - correction for function wc_get_page_id()
function woocommerce_translate_polylang_page_id($pageid) {
	if (!empty($pageid)) {
		if (PLL() instanceof PLL_Frontend) {
			$pllpageid = pll_get_post($pageid);
			if (!empty($pllpageid)) {
				$pageid = $pllpageid;
			}
		}
	}
	return $pageid;
}
//myaccount, edit_address, shop, cart, checkout, pay, view_order, terms
add_filter( 'woocommerce_get_myaccount_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_edit_address_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_shop_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_cart_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_checkout_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_pay_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_view_order_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );
add_filter( 'woocommerce_get_terms_page_id', array( $this, 'woocommerce_translate_polylang_page_id' ), 10, 1 );

Have a nice day!

HTTP Error 413.1 – Request Entity Too Large – The page was not displayed because the request entity is too large.
Large file? Large problem! On IIS you can get this error while trying to upload. Read this and then think… maybe edit the web.config file in the root? So you try adding this, or something similar:

<serverRuntime>
  <uploadReadAheadSize>2147483647</uploadReadAheadSize>
</serverRuntime>
<security>
  <requestFiltering>
    <requestLimits>
      <maxAllowedContentLength>2147483647</maxAllowedContentLength>
    </requestLimits>
  </requestFiltering>
</security>

but you simply get: HTTP Error 500.19 – Internal Server Error – The requested page cannot be accessed because the related configuration data for the page is invalid. – so, whatever you were thinking is: Wrong!
When using IIS manager you get:

<security>
  <requestFiltering>
    <requestLimits maxAllowedContentLength="2147483647" />
  </requestFiltering>
</security>

while the ‘uploadReadAheadSize’ does not appear anywhere in the web.config. But: it helps and there are no more errors while uploading!
So you have to set these values in IIS Manager itself.
Problem? Solved!

Have a nice day!
