 ======How to Fix Image Optimization Errors ======
 There are a number of different warning/error messages you may see after you've sent an image optimization request. This is your guide to those messages.

+Other things you may need to check:
+  - Security plugins may intervene the image optimization process, try disable it temporarily
+  - Plugins that controls page access, like maintenance mode , spam shield , additional authentications page , altering the HTTP/HTTPS schemes, hot-link protection rewrite rule ...etc , these features could also intervene the image optimization, if you have these , try disable them temporarily.
 ===== Too Many Errors =====

 Now the **Update Reduction Status** button should work fine.
+===== Image Groups Notified / Pull Never Works =====
+==== Error Details ====
+The screen displays ''Image groups notified to pull: X'', but the images are never pulled. A cron job starts for a few minutes, but the notified image groups number remains the same.
+The debug log shows:
+<code>IAPI failed to decode post json: "missed data"
+Media: Failed to pull optimized img: --- '"missed data"'</code>
+==== Solution ====
+The issue is due to data expiration. The image optimization server keeps optimized images for 20 days. If not pulled within 20 days, the images are removed. However, the client side is not aware that the images are missing, so it keeps trying to pull images that no longer exists on the server.
+The only solution is to destroy all optimization data and re-do it.
+===== Failed to push to LiteSpeed IAPI server =====
+==== Error Details ====
+The screen displays ''Failed to push to LiteSpeed IAPI server: "Too many errors while fetching image source files for previous request."''
+==== Solution ====
+Press the **Clean Up Unfinished Data** button, and then press the refresh icon next to **Optimization Summary**. You should now be able to send a new optimization request.

+===== Error when handling your previous requests =====
+==== Error Details ====
+This error is similar as above one, and displays ''Error when handling your previous requests [Send request to reset fetch error count]''
+==== Solution ====
+Press the **Send request to reset fetch error count** button in notification bar. Then, press the **Clean Up Unfinished Data'** button, and press the refresh icon next to **Optimization Summary**. You should now be able to send a new optimization request.

+===== Lot Of Images Pushed And Pulled Back Immediately  =====
+==== Error Details ====
+When you send an optimization request, it returns a success message, and then all of the images are immediately pulled without having been optimized.
+You will also see a message like ''Missing: XX groups (YY images)'' on the optimization page.
+The debug log shows the following:
+<code>07/21/18 18:07:17.125 [IP:26247 1 gmZ] [Img_Optm] bypass image due to file not exist: pid 3434 /website/wp-content/uploads/2017/09/1-768x910.jpg</code>
+This is typically due to a change in the image file path, for example in a WordPress site migration, where the file moves, but the database is not properly updated. When LSCWP uses the database to look for the images, it will not find them and will report them missing.
+==== Solution ====
+Update or repair the WordPress database.
+===== cURL error 28: Operation timed out after 15001 milliseconds with 0 bytes received  =====
+==== Error Details ====
+Firewall blocked curl communication to our image optimization servers.
+==== Solution ====
+Add our image optimization server [[https://wp.api.litespeedtech.com/ips|IPs]] to firewall white-list.
