 * Hi,
 * So I’ve been using this plugin for ages now and it’s been super cool all the 
   time. So thank you for that.
 * However, there seems to be an issue on one site that I am trying to change URLs
   on.
 * When I run the plugin against the wp_options table that is around 1.5MB in the
   plugin outputs a 500 error. So I dug into the plugin and I was able to output
   the data in an error txt file to locate why the issue is happening.
 * So I changed the Max Page Size to only 1 and also edited the /includes/class-
   bsr-db.php file on line 220 to insert my debugging code:
 * if($row[‘option_name’] == ‘uninstall_plugins’){
    continue; } $file = plugin_dir_path(
   __FILE__ ) . ‘/errors.txt’; $current = file_get_contents($file); ob_start(); 
   var_dump($row); $ott = ob_get_clean(); $current .= $ott.”\n”; file_put_contents(
   $file, $current);
 * So this code above outputs the rows that are processed by the plugin for example:
 * array(4) {
    [“option_id”]=> string(6) “105296” [“option_name”]=> string(30) “
   _transient_w3tc.verify_plugins” [“option_value”]=> string(1) “1” [“autoload”]
   => string(2) “no” }
 * But when the plugin gets to this option name “uninstall_plugins” it basically
   is unable to process the data, now I overcome the issue by skipping just that
   option.
 * Here is the data that is in that table
 * O:8:”stdClass”:3:{s:9:”lastCheck”;i:1572007478;s:14:”checkedVersion”;s:6:”3.2.10″;
   s:6:”update”;O:8:”stdClass”:9:{s:2:”id”;i:0;s:4:”slug”;s:7:”aioseop”;s:7:”version”;
   s:6:”3.2.10″;s:8:”homepage”;s:26:”[https://semperplugins.com/&#8221](https://semperplugins.com/&#8221);;
   s:6:”tested”;s:5:”5.2.4″;s:12:”download_url”;s:78:”[https://semperplugins.com/store/receipt/?duid=dda92c5e327223ecbf7d90ae7c6a4447&#8243](https://semperplugins.com/store/receipt/?duid=dda92c5e327223ecbf7d90ae7c6a4447&#8243);;
   s:14:”upgrade_notice”;s:26:”Improvements and bug fixes”;s:8:”filename”;s:47:”
   all-in-one-seo-pack-pro/all_in_one_seo_pack.php”;s:12:”translations”;a:0:{}}}
 * I just want to know why its craching only on this, is there something wrong in
   the serialized data?
 * Thanks!
