Title: Endless Progress Bar Last modified: March 10, 2017 --- # Endless Progress Bar * Resolved [emcrit](https://wordpress.org/support/users/emcrit/) * (@emcrit) * [9 years, 2 months ago](https://wordpress.org/support/topic/endless-progress-bar/) * When I activate wpdiscuz on my site, I cannot leave comments as either a guest or logged in user. Everything looks fine until you hit submit, at that point progress bar appears in the upper right of the screen and stays indicating progress( lack of) forever. Comment never gets submitted. Troubleshooting so far: * disabled all other plugins * tried with disabled plugins and default wordpress theme * went to firefox console-no JS errors * site is emcrit.org (currently plugin is disabled–otherwise nobody can comment) * would appreciate any help! * thanks, Scott Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [gVectors Team](https://wordpress.org/support/users/gvectors-team/) * (@gvectors-team) * [9 years, 2 months ago](https://wordpress.org/support/topic/endless-progress-bar/#post-8897293) * I think problem comes from caching and content minification. Install wpDiscuz back and delete all cache of WP Rocket, then play with WP Rocket options. I think this is a cache issue. * Plugin Author [gVectors Team](https://wordpress.org/support/users/gvectors-team/) * (@gvectors-team) * [9 years, 2 months ago](https://wordpress.org/support/topic/endless-progress-bar/#post-8897302) * Also please let us know what hosting service you use. * [ccrim](https://wordpress.org/support/users/ccrim/) * (@ccrim) * [9 years, 2 months ago](https://wordpress.org/support/topic/endless-progress-bar/#post-8898539) * I’m experiencing the same issue on my own server. (crimdom.net) I do not have WP Rocket. * Tried deleting and reinstalling wpdiscuz and problem of “endless progress bar” returned immediately. Also encountered errors during attempt to reinstall (“server not responsive”). I’ve now deactivated wpdiscuz. * [ccrim](https://wordpress.org/support/users/ccrim/) * (@ccrim) * [9 years, 2 months ago](https://wordpress.org/support/topic/endless-progress-bar/#post-8898811) * I just tried commenting via FireFox and I see the following error: “SyntaxError: JSON.parse: unexpected character at line 2 column 3 of the JSON data” * Notably, there is a very thin pink error bar after trying to submit a comment via Safari but there’s no error message visible. * Plugin Author [gVectors Team](https://wordpress.org/support/users/gvectors-team/) * (@gvectors-team) * [9 years, 2 months ago](https://wordpress.org/support/topic/endless-progress-bar/#post-8898913) * Please let me know the PHP version and Hosting Service name.

No Hosting Service name as this is my own server (crimdom. net). Deactivate all plugins and install again? Even though it was previously working?
