SharePoint Online: Unable to create custom form – Could not save the list changes to the server

I am not able to create custom form for any list across the whole tenant and getting the error:

“Could not save the list changes to the server”.

I am working in SharePoint online and using SP Designer 2013. I am the site collection administrator.

It was working before and stopped working a few days back. I have tried following things but the issue is yet not resolved:

1) Checked “Allow custom scripts” from admin center.

2) Add and customize pages permission is granted.

3) Cleared designer cache.

4) Checked using another site collection administrator account.

Unable to get property ‘PageManager’ of undefined or null reference SP2013

I’ve just created a new custom list on my site, with a simple list, one text column, no javascript, no CEWP, just a very basic vanilla function.

Running the page with PF12 open, the error “Unable to get property ‘PageManager’ of undefined or null reference” comes up.

Is this normal? What is causing this? Any fix?

Unable to view Mageplaza extension configuration page. A blank page is displayed instead of configuration page

I have installed Mageplaza SMTP extension in my magento site (v 2.3.1). The problem I am facing is that I am unable to see its configuration page when I try to access it from Stores >> Configuration >> Mageplaza >> Smtp

The problem doesnot happen only with SMTP extension. I have tried Google Recaptcha of Mageplaza and it is showing me the same issue.

Instead of showing the configuration page in backend its showing a blank page.

Unable to connect through VNC

I’m trying to configure VNC server on my Ubuntu 19.04 desktop so that I can connect to it through my windows laptop over home wifi. I followed steps mentioned https://www.cyberciti.biz/faq/install-and-configure-tigervnc-server-on-ubuntu-18-04/

My firewall is inactive and I am unable to connect from my laptop. I tried to connect from local vnc viewer using 127.0.0.1:5902 and it connects.

But if I give local-lan-ip:5902 I see the error “unable to connect to socket:connection refused”

I’m really not a pro at configuring stuff on linux, can someone help me figure out the issue ?

SharePoint 2016 unable to crawl new version PDF files

I am setting up a SP2016 on-premise farm. Some pdf files with newer version cannot be crawled. Here is my findings:

  1. Those pdf files are v1.7 (Acrobat 8.x, Acrobat 9.x)
  2. Search only return those pdf by search with file name. Search with pdf content will not return result.
  3. In the search result page, those files preview show

“If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document … You can upgrade to the latest …”

  1. In the crawl log, those files are shown up as warning. Error is “Document was partially processed.”

Should I install pdf viewer on the crawling server to solve the problem?

Unable to host Speech Recognition and Sound Playing Application on Docker

I have an application that takes voice input from microphone, performs speech recognition and plays certain music files based on the cue words recognized. This application is in Python and implements a couple of python modules like PyAudio, Playsound and Websocket-client. I am trying to build a Docker image of this application.

I have created a Dockerfile with below contents:

FROM ubuntu ADD . /app  FROM python:3 ADD transcribe.py / ADD speech.cfg / ADD setup.cfg /  ADD setup.py /  RUN apt-get update RUN apt-get --assume-yes install libasound-dev portaudio19-dev     libportaudio2 libportaudiocpp0 RUN pip3 install pyaudio RUN pip3 install websocket-client RUN pip3 install playsound CMD [ "python3", "./transcribe.py" ] 

When trying to build it, I get a successful build response as below:

Unable to delete video on Sharepoint Library

I’m trying to delete a video file that is saved inside a SharePoint online library and always gives me the error “You have to delete all the items in this folder before you can delete the folder“. The user has the permissions to do it, also the item is not locked or check out.

I try deleting the file from SharePoint Designer and I can see that the video is actually a folder that has:

  1. Video File
  2. Folder: “Preview Images”
  3. Folder: “Additional Content”

If I delete each folder and file from here. I was able to finally delete the video from the library, but this is not a solution, for all the users.

Has anyone experience something like that?
