  <p>Can anyone help me to solve it... or reindex correctly?</p>
  
  <p>I have also tried increasing time limit, memory limit, skipping security, etc. but didn't work as I wrote in .htaccess file:</p>
  
  <pre><code>   php_value memory_limit 2836M
     php_value max_execution_time 2592000
     php_value max_input_time 2592000
     php_value session.gc_maxlifetime 864000
     php_value session.cookie_lifetime 864000
     php_value max_input_vars 50000
