 * Hi. I’m troubling for long time about apache errors and i diagnosed what is causing
   the problem.
 * Error is this:
 * [Thu Mar 07 10:20:36.954194 2019] [core:error] [pid 4745:tid 140475813943040][
   client] AH00125: Request exceeded the limit of 10 subrequest nesting levels due
   to probable configuration error. Use ‘LimitInternalRecursion’ to increase the
   limit if necessary. Use ‘LogLevel debug’ to get a backtrace., referer:
 * This problem persists even if i disable all of plugins except W3TC.
 * Other problem is compability with Ultimate Member. When i use CSS Minify option
   then site theme breaks and loades very slow. I tried changing minificators from
   general menu but nothing is changing.
 * Is there help for this?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Frewrite-url-structure-causing-apache-redirect-loop-errors-and-um-css-compability%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello,
    Go to Performance>Minify and deselect Rewrite URL structure box. Save
   all settings and see if the issue persists. If the issue persists, GO to Performance
   >Page cache and scroll down to Advanced sub-box. Check the “Compatibility mode:”
   box and save all settings. Also, check if the issue persists after this step.

 * Of course i deselected earlier Rewrite URL structure and apache problem is resolved
   but performance is worse. How to diagnose this so that this option could be enabled?
 * As for Ultimate Member – nothing helps except disabling css minify

 * Hello,
    Have you tried to Check the “Compatibility mode:” box and save all settings
   while Rewrite URL is enabled? As for the Ultimate Member, is minify enabled on
   Auto? if so you need to exclude certain parts from being minified.

 * YEs.

 * I don’t know how to diagnose this parts/files which are creating problem. One
   we know is the plugin and css files

 * Hello,
    Please share your .htaccess file. We’ll inspect it and see if maybe something
   is wrong with the rules in it. Also please run compatibility check in Performance
   >Dashboard.

 * Even i can’t inline css in html minify options
 * And i must disable java script minify to ultimate member to work! If not it has
   blank pages

 * Ok it worked when i add pages not to minify but now these pages are very slow.
   I think we must type specific files js+css to be not minified or combined. But
   which?
 * You may check slowness here `http://swiadomosc-zwiazkow.pl/uzytkownik/redpillerpl/`
 * As for for not redirecting/rewriting rules i disabled Optimize disk enhanced 
   page and minify disk caching for NFS

 * Hello,
    So when you disabled `Optimize disk enhanced page and minify disk caching
   for NFS` the rewrite issue is gone? Have you checked this post for excluding 
   pages? [https://wordpress.org/support/topic/w3-total-cache-conflict-11/](https://wordpress.org/support/topic/w3-total-cache-conflict-11/)

 * Yes. Problem with apache is solved. Without this option performance is very bad
   for CPU usage.

 * Hello,
    If you need that option, that means that you are using NFS file system
   server. It’s not easy to change that and recommended not to do so. Disabling 
   that option means that the plugin has issues finding and generating the correct
   directory structure, that’s why there are performance issues

 * True. We know the cause but we don’t know how to solve it. Whole time i have 
   apache errors
    Request exceeded the limit of 10 subrequest nesting levels due
   to probable configuration error
