Comment (by davidfhannes):

 I'm told this is the correct thread to ask my question(s):

 I have a Woo Commerce website with very large menu structure for the nav
 bar. Recently when I tried to add to the menu structure under
 appearances...Menu and press update the page...the page processes and then
 crashes and gives me a 404 page cannot be found error even though it is
 the same page.

 My server provider informs me that the postmeta_wp table has 2 million
 rows.

 I went to Woo Commerce…System Status…Tools and cleared the following:

 WC Transients
 Expired Transients
 Customer Sessions

 Still not resolved.

 I have run 2 optimization plugins to no avail to clean out the 2 million
 rows.

 I have added this line to php.ini, which resolved another menu problem,
 but it does not resolve this: max_input_vars = 3000

 Question: Are there things we can do to the settings under PHP
 Configuration editor on the server or php.ini to resolve this?
