 * Hi there 🙂
 * I’m having a compatibility issue with the plugin [WP/LR](https://de.wordpress.org/plugins/wplr-sync/)(
   for uploading files directly from Adobe Lightroom into WordPress).
 * The upload works fine when W3 is disabled. When I enable it, I get the following
   PHP-Error in the WordPress error_log: explode() expects parameter 2 to be string,
   array given in [exact file and line].
 * Some information from the developer: WP/LR Sync needs access to the WP-JSON API,
   and it also uses the wp_authenticate function to resolve your credentials.
 * I already tried the following without success:
    – Make sure REST API is set to“
   Don’t cache” – Disable Page Caching entirely – Disable Minify entirely – Disabling
   all extensions (Cloudflare and Fragment Cache)
 * Oh, and I’ve never had any issues so far with W3 and WP/LR, until I updated the
   Plugin. I can’t tell which update exactly since I haven’t updated for a while
   and then probably “skiped” some versions.
 * Can anyone help me out with this?
 * Kind regards
    Nico

 * Hello [@nicokobel](https://wordpress.org/support/users/nicokobel/)
 * I am sorry about the issue you are experiencing and I am happy to assist you 
   with this.
    When you say you updated the plugin, can you please specify which
   plugin you are referring to? W3TC or WP/LR? To confirm, the issue is gone after
   you disable W3 Total Cache. Have you tried disabling all settings in Performance
   >General settings and see if the issue is resolved after that, and then re-enable
   the settings one by one and see which setting might be causing the issue? Thanks!
