@Aftabuzzaman: If you would like to try making this configuration change yourself, please follow https://wikitech.wikimedia.org/wiki/Wikimedia_site_requests#Change_the_logo_of_a_Wikimedia_wiki and give it a try.
@Urbanecm Sorry for asking this now, but I need your help again. We need to reupload this patch again with the current version of : https://commons.wikimedia.org/wiki/File:Wikipedia-logo-v2-bn.svg
After you closed this task, I was working on creating a Bengali wordmark for the mobile site. While doing that, I noticed that my uploaded version had a small problem. Basically, some parts (curves) of some letters weren't smooth (example here, marked in yellow). If we didn't fix it and then used it, for example, in a big banner, then it would look bad. So I had to fix it and reupload it. I also notified the community about this and no objection was raised there about this fix.
Could you please reupload this patch with the current version (or should I create a new task for it?)
