Installation worked now but I still get the same message. * This is what I did: De-activated the existing LSCache Plugin. Renamed the plugin folder via ftp. Installed and activated the new version, following your instructions. Had a short look at the setting – they seem to be the same as before. * I also installed the plugin on my development site, with the same settings as on the live site. There I don’t get the message (but I don’t have enough images/“ credits” there so I’m not sure if auto optimization would be triggered). * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [7 years, 8 months ago](https://wordpress.org/support/topic/failed-to-parse-data-from-litespeed-iapi-server-array/#post-10594463) * Hi, * We are working on the next release which includes some image optimization fix and improvement. * Please wait for next release. * Best regards, * Thread Starter [Thomas](https://wordpress.org/support/users/thiomas/) * (@thiomas) * [7 years, 7 months ago](https://wordpress.org/support/topic/failed-to-parse-data-from-litespeed-iapi-server-array/#post-10633864) * Thanks. 2.4.3 solved the problem. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [7 years, 7 months ago](https://wordpress.org/support/topic/failed-to-parse-data-from-litespeed-iapi-server-array/#post-10633902) * Hi, * Glad to know it works for you now. * Would you like to leave us a [review](https://wordpress.org/support/plugin/litespeed-cache/reviews/)? * Your support and feedback would make LSCWP better 🙂 * Best regards, Viewing 13 replies - 1 through 13 (of 13 total) The topic ‘Failed to parse data from LiteSpeed IAPI server: Array’ is closed to new replies. * ![](https://ps.w.org/litespeed-cache/assets/icon-256x256.png?rev=2554181) * [LiteSpeed Cache](https://wordpress.org/plugins/litespeed-cache/) * [Frequently Asked Questions](https://wordpress.org/plugins/litespeed-cache/#faq) * [Support Threads](https://wordpress.org/support/plugin/litespeed-cache/) * [Active Topics](https://wordpress.org/support/plugin/litespeed-cache/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/litespeed-cache/unresolved/) * [Reviews](https://wordpress.org/support/plugin/litespeed-cache/reviews/) * 13 replies * 3 participants * Last reply from: [qtwrk](https://wordpress.org/support/users/qtwrk/) * Last activity: [7 years, 7 months ago](https://wordpress.org/support/topic/failed-to-parse-data-from-litespeed-iapi-server-array/#post-10633902) * Status: resolved
